IBM IBM WebSphere Process Server

WebSphere vs. .net: IBM and Microsoft Go head to head

After accomplishing a number of benchmarks, Microsoft concluded that .internet offers more suitable performance and price-efficiency ratio than WebSphere. IBM rebutted Microsoft’s findings and performed other tests proving that WebSphere is sophisticated to .web. Microsoft replied by using rejecting some of IBM’s claims as false and repeating the checks on diverse hardware with different outcomes.

abstract

Microsoft has benchmarked .net and WebSphere and published the benchmark source code, run guidelines, use suggestions and a findings report published at wholoveswindows.com entitled Benchmarking IBM WebSphere 7 on IBM Power6 and AIX vs. Microsoft .web on HP BladeSystem and home windows Server 2008.   This benchmark shows a lots larger transactions per 2nd (TPS) cost and enhanced charge/performance ratio when using WebSphere 7 on windows Server 2008 over WebSphere on AIX 5.three, and even more advantageous effects when the use of .web on home windows Server 2008 over WebSphere on the equal OS. The can charge/performance ratio for the application benchmark used is:

IBM power 570 with WebSphere 7 and AIX 5.3 HP BladeSystem C7000 with WebSphere 7 and windows Server 2008 HP BladeSystem C7000 with .web and windows Server 2008 $32.45 $7.ninety two $three.99

IBM has rebutted Microsoft’s benchmark and called some of their claims as false, and carried out a distinct benchmark, with distinctive effects. The benchmark used together with the findings were posted in Benchmarking AND BEATING Microsoft’s .net three.5 with WebSphere 7! (PDF). The supply code of the benchmark became now not published. The outcomes show WebSphere as a more robust performing middle-tier than .internet with 36% more TPS for one application benchmark and from 176% to 450% more advantageous throughput for one of IBM’s ordinary benchmarks.

Microsoft replied to IBM and defended their claims and benchmarking results with Response to IBM’s Whitepaper Entitled Benchmarking and Beating Microsoft .net 3.5 with WebSphere 7 (PDF). Microsoft has also re-run their benchmark, modified to consist of a different check circulation similar to the one used via IBM in their checks, working it on distinctive hardware, a single multi-core server, founding that indeed WebSphere is greater than .net if the use of IBM’s verify move but only a little bit more advantageous, between three% and %6, no longer as mentioned by using IBM. anyway that, these later findings do not exchange the usual ones on account that the benchmark turned into run on a different hardware configuration. in the conclusion, Microsoft invites IBM to “an impartial lab to operate additional testing”.

Microsoft checking out .internet towards WebSphere

Microsoft has carried out a series of tests evaluating WebSphere/Java against .internet on three distinctive systems. The particulars of the benchmarks performed and the check consequences had been posted within the whitepaper entitled Benchmarking IBM WebSphere® 7 on IBM® Power6™ and AIX vs. Microsoft® .web on Hewlett Packard BladeSystem and windows Server® 2008 (PDF).

systems validated:

  • IBM power 570 (vigour 6) running IBM WebSphere 7 on AIX 5.three
  • eight IBM Power6 cores at four.2GHz
  • 32 GB RAM
  • AIX 5.3
  • four x 1 GB NICs
  • Hewlett Packard BladeSystem C7000 running IBM WebSphere 7 on home windows Server 2008
  • 4 Hewlett Packard ProLiant BL460c blades
  • One Quad-Core Intel® Xeon® E5450 (3.00GHz, 1333MHz FSB, 80W) Processor/blade
  • 32 GB RAM/blade
  • home windows Server 2008/sixty four-bit/blade
  • 2 x 1 GB NICs/blade
  • Hewlett Packard BladeSystem C7000 working .web on windows Server 2008
  • equal because the old one however the purposes confirmed run on .web instead of WebSphere.
  • a few three exams had been performed on every platform:

  • exchange net application Benchmarking The functions proven have been IBM’s alternate 6.1 and Microsoft’s StockTrader 2.04. This sequence of checks have evaluated the efficiency of complete data-pushed internet functions running on accurate of the above outlined structures. The net pages accessed had one or continually greater operations serviced by using courses contained by way of the enterprise layer and ending with synchronous database calls.
  • alternate center Tier web capabilities Benchmarking This benchmark become meant to measure the performance of the internet provider layer executing operations which ended up in database transactions. The test turned into similar to web software, but operations were counted personally.
  • WS check net features Benchmarking This examine became like the previous one but there became no company logic nor database access. This changed into according to WSTest workload initially devised by way of solar and augmented through Microsoft. The features tier provided three operations: EchoList, EchoStruct and GetOrder. Having no business common sense, the check measured best the raw efficiency of the internet provider application.
  • Two database configurations have been used, one for the all-IBM platform and a different for the other two: IBM DB2 V9.5 enterprise version with IBM DB2 V9.5 JDBC drivers for facts entry and SQL Server 2008 databases business version. Two databases have been set up for every configuration working on HP BL680c G5 blades:

  • four Quad-Core Intel XEON CPUs, @2.4GHZ (sixteen cores in every blade)
  • 64 GB RAM
  • four x 1GB NICs
  • IBM DB 9.5 enterprise version sixty four-bit or Microsoft SQL Server 2008 64-bit
  • Microsoft windows Server 2008 64-bit, enterprise version
  • 2 4GB HBAs for fiber/sans access to the EVA 4400 storage
  • The storage changed into secured on HP StorageWorks EVA 4400 Disk Array:

  • ninety six 15K drives total
  • four logical volumes consisting of 24 drives every
  • Database server 1: Logical quantity 1 for logging
  • Database server 1: Logical volume 2 for database
  • Database server 2: Logical volume 3 for logging
  • Database server 2: Logical extent four for database
  • The internet application benchmark used 32 customer machines running test scripts. each and every laptop simulated tons of of valued clientele having a 1 second consider time. The assessments used an tailored version of IBM’s alternate 6.1 utility on SUT #1 & #2 and Microsoft’s StockTrader software on SUT #three.

    image

    For the web service and WSTest benchmarks, Microsoft used 10 shoppers with a 0.1s suppose time. For WSTest, the databases had been no longer accessed. Microsoft has created a WSTest-compliant benchmark for WebSphere 7 and JAX-WS and an extra in C# for .web using WCF.

    image

    Microsoft’s whitepaper contains greater details on how the checks were conducted including the DB configuration, DB access used, caching configuration, verify scripts, tuning parameters used and others.

    Conclusion

    The benchmarking outcomes together with the charges/efficiency ratio are proven in the following desk:

      IBM energy 570 with WebSphere 7 and AIX 5.three HP BladeSystem C7000 with WebSphere 7 and windows Server 2008 HP BladeSystem C7000 with .internet and windows Server 2008 complete core-Tier device can charge $260,128.08 $87,161.00 $50,161.00 trade net utility Benchmark eight,016 TPS eleven,004 TPS 12,576 TPS cost/performance $32.45 $7.92 $3.99 exchange core Tier web service Benchmark 10,571 TPS 14,468 TPS 22,262 TPS charge/performance $24.sixty one $6.02 $2.25 WSTest EchoList examine10,536 TPS 15,973 TPS 22,291 TPS can charge/performance $24.69 $5.46 $2.25 WSTest EchoStruct examineeleven,378 TPS 16,225 TPS 24,951 TPS charge/efficiency $22.86 $5.37 $2.01 WSTest GetOrder examineeleven,009 TPS 15,491 TPS 27,796 TPS cost/performance $23.63 $5.63 $1.eighty

    in accordance with Microsoft’s benchmarking results, working WebSphere on HP BladeSystem with windows Server 2008 is set 30% greater productive and the cost-performance ratio is 5 times lessen than running WebSphere on IBM energy 570 with AIX 5.3. The .web/windows Server 2008 configuration is much more productive and the cost/performance ratio drops to half in comparison to WebSphere/home windows Server 2008 and it is 10 times smaller than WebSphere/energy 570/AIX. The can charge-efficiency ratio is so high for the primary platform because the rate of the complete middle-tier is over $250,000 whereas the efficiency is decrease than the other structures.

    Microsoft’s benchmarking whitepaper (PDF) contains an appendix with comprehensive details of the hardware and utility expenses. The benchmarking exams used, together with supply code, are posted on StockTrader web page.

    IBM’s Rebuttal

    In another paper, Benchmarking AND BEATING Microsoft’s .internet 3.5 with WebSphere 7! (PDF), IBM has rejected Microsoft’s benchmark and created yet another one showing that WebSphere is performing more advantageous than .internet.

    Microsoft had noted that StockTrader is similar to IBM’s trade application:

    Microsoft created an software it's functionally corresponding to the IBM WebSphere exchange software, both in terms of consumer performance and middle-tier database access, transactional and messaging behavior.

    IBM rejected Microsoft’s claim:

    The utility claims to be “functionally equal” to the IBM WebSphere change 6.1 sample software. It is not a “port” of the software in any sense. Little, if any, of the customary utility design changed into ported. Microsoft has made this an application that showcases the use of its proprietary applied sciences. a tremendous indication of here is the proven fact that the .net StockTrader utility is not a universally accessible web utility considering that it will possibly simplest be accessed by using cyber web Explorer, and never by other internet browsers.

    moreover, IBM noted that alternate become no longer designed to benchmark WebSphere’s efficiency but reasonably to

    serve as a pattern application illustrating the usage of the elements and functions contained in WebSphere and how they concerning utility performance. moreover, the software served as a pattern which allowed builders to explore the tuning capabilities of WebSphere.

    IBM had different complaints regarding Microsoft’s benchmark:

    Microsoft created a totally new application [StockTrader] and claimed practical equivalence at the software stage. The fact is that the Microsoft edition of the application used proprietary SQL statements to entry the database, not like the original edition of alternate 6.1 which became designed to be a conveyable and common software.

    They employed customer facet scripting to shift probably the most application feature to the customer.

    They tested web capabilities capabilities by inserting an unnecessary HTTP server between the WebSphere server and the client.

    And If that turned into no longer adequate, they didn't accurately monitor and modify the WebSphere utility server to obtain peak efficiency.

    IBM’s aggressive project workplace team (CPO) has ported StockTrader 2.0 to WebSphere creating CPO StockTrader and claiming: “we did a port that faithfully reproduced Microsoft’s software design. The intent became to achieve an apples-to-apples evaluation.” So, trader 6.1 was ported by way of Microsoft from WebSphere to .web beneath the name StockTrader and ported once more through IBM returned to WebSphere below the name CPO StockTrader. IBM benchmarked CPO StockTrader against StockTrader and bought better effects for WebSphere in opposition t .web:

    image

    IBM has additionally informed they are using friendly bank, an application supposed to benchmark WebSphere in opposition t .internet. in this examine WebSphere outperforms .internet a few times:

    image

    of their StockTrader vs. CPO StockTrader benchmark, IBM used scripts simulating person undertaking: “login, getting costs, stock purchase, inventory promote, viewing of the account portfolio, then a logoff” and running in stress mode devoid of believe instances. 36 clients had been simulated, ample to power each server at highest throughput and utilization. The information back become validated and errors had been discarded.

    The front conclusion become carried out with WebSphere 7/windows Server 2008 in one case and .net three.5 with IIS 7/home windows Server 2008 within the other. The returned end database turned into DB2 8.2 and SQL Server 2005, both on home windows Server 2003.

    The hardware used for checking out become:

    performance trying out device HardwareX345 8676 Server2 X 3.06 GHz Intel Processor with Hyper Thread Technology8 GB RAM18.2 GB 15K rpm SCSC challenging Disk Drive1 GB Ethernet interfaceApplication Server Hardware IBM X3950 Server, eight x three.50 Ghz, Intel Xeon Processors with Hyper Thread technology, sixty four GB RAMDatabase Server HardwareX445 8670 Server, 8x three.0 Ghz.

    The software and hardware configuration for the friendly bank benchmark changed into comparable to the StockTrader one.

    IBM’s whitepaper carries counsel in regards to the friendly bank utility, however doesn't aspect to the source code. It also mentions that the utility changed into at the beginning designed for .net Framework 1.1 and changed into simply recompiled on .net three.5 with out being updated to make use of the newest applied sciences.

    Microsoft Response to IBM’s Rebuttal

    Microsoft has responded to IBM’s rebuttal in yet an extra whitepaper, Response to IBM’s Whitepaper Entitled Benchmarking and Beating Microsoft .web three.5 with WebSphere 7 (PDF). in this doc, Microsoft defends their customary benchmarking results and affirms that IBM made some false claims of their rebuttal document entitled Benchmarking AND BEATING Microsoft’s .net 3.5 with WebSphere 7!, and IBM didn't use an acceptable benchmarking procedure.  more has been posted at wholoveswindows.com.

    truly, Microsoft spoke of here claims are false:

  • IBM declare: The .internet StockTrader doesn't faithfully reproduce the IBM exchange software functionality.Microsoft response: this claim is fake; the .net StockTrader 2.04 faithfully reproduces the IBM WebSphere trade software (the usage of standard .net Framework applied sciences and coding practices), and may be used for reasonable benchmark comparisons between .internet 3.5 and IBM WebSphere 7.
  • IBM claim: The .net StockTrader makes use of customer-side script to shift processing from the server to the customer.Microsoft response: this declare is fake, there isn't any customer-aspect scripting in the .net StockTrader application.
  • IBM claim: The .internet StockTrader uses proprietary SQL.Microsoft response: the .web StockTrader uses usual SQL statements coded for SQL Server and/or Oracle; and offers a knowledge access layer for both. The IBM WebSphere 7 exchange software in a similar fashion makes use of JDBC queries coded for DB2 and/or Oracle. Neither implementation uses kept techniques or services; all company good judgment runs within the application server. primary pre-prepared SQL statements are used in both applications.
  • IBM claim: The .net StockTrader isn't programmed as a universally accessible, skinny-customer internet application. therefore it runs best on IE, no longer in Firefox or different browsers.Microsoft response: definitely, the .internet StockTrader internet tier is programmed as a universally obtainable, pure skinny customer web utility. although, a simple situation in theuse of HTML remark tags causes concerns in Firefox; these remark tags are being up-to-date to permit the ASP.web utility to safely render in any industry typical browser, together with Firefox.
  • IBM declare: The .web StockTrader has blunders under load.Microsoft response: here's false, and this document comprises further benchmark assessments and Mercury LoadRunner details proving this IBM declare to be false.
  • also, Microsoft complained that IBM had developed pleasant bank for .internet Framework 1.1 years ago using obsolete applied sciences:

    IBM’s pleasant financial institution benchmark makes use of an out of date .web Framework 1.1 software that comprises applied sciences comparable to DCOM that have been out of date for a long time. This benchmark should be fully discounted until Microsoft has the opportunity to overview the code and replace it for .net 3.5, with more moderen applied sciences for ASP.internet, transactions, and home windows verbal exchange groundwork (WCF) TCP/IP binary remoting (which replaced DCOM because the favorite remoting expertise).

    Microsoft regarded IBM failed through no longer featuring the supply code for CPO StockTrader and friendly bank functions and reiterated the fact that all of the source code for Microsoft’s benchmark applications worried in this case had been made public.

    Microsoft additionally observed that IBM had used a modified test script which “protected a heavier emphasis on buys and additionally covered a promote operation”. Microsoft re-carried out their benchmark the usage of IBM’s modified verify script circulation, one together with the operations purchase and promote beside Login, Portfolio, Logout, on a single four-core utility server maintaining that

    these assessments are in keeping with IBM’s revised script and are meant to fulfill some of those IBM rebuttal look at various situations as outlined in IBM’s response paper. They should not be regarded in any means as a transformation to their usual effects (carried out on diverse hardware, and diverse test script stream); because the normal outcomes remain legitimate.

    The verify turned into carried on:

    utility Server(s) Database(s) 1 HP ProLiant BL460c1 Quad-core Intel Xeon E5450 CPU (three.00 GHz)32 GB RAM2 x 1GB NICsWindows Server 2008 sixty four-bit.internet three.5 (SP1) 64-bitIBM WebSphere 64-bit 1 HP ProLiant DL380 G52 Quad-core Intel Xeon E5355 CPUs (2.67 GHz)64 GB RAM2 x 1GB NICsWindows Server 2008 64-bitSQL Server 2008 64-bitDB2 V9.7 sixty four-bit

    The outcome of the check shows identical efficiency for WebSphere and .net.

    image

    one among IBM’s complaints had been that Microsoft inserted an unnecessary HTTP web server in entrance of WebSphere decreasing the number of transactions per 2nd. Microsoft admitted that, but delivered:

    the use of this HTTP Server changed into wholly discussed in the fashioned benchmark paper, and is carried out in response to IBM’s personal most desirable apply deployment instructions for WebSphere. In any such setup, IBM recommends the usage of the IBM HTTP Server (Apache) as the entrance conclusion web Server, which then routes requests to the IBM WebSphere software server. In their tests, they co-discovered this HTTP on the same computing device as the application Server. here's comparable to the .internet/WCF web service exams, where they hosted the WCF web services in IIS 7, with co-determined IIS 7 HTTP Server routing requests to the .net software pool processing the WCF provider operations. So in each checks, they demonstrated an equivalent setup, using IBM HTTP Server (Apache) as the front conclusion to WebSphere/JAX-WS functions; and Microsoft IIS 7 as the front conclusion to the .web/WCF services. therefore, they stand at the back of all their normal outcomes.

    Microsoft performed yet a further examine, the WSTest, devoid of the middleman HTTP internet server on a single quad-core server just like the old one, and acquired here outcome:

    image

    both exams performed by way of Microsoft on a single server show WebSphere preserving a mild performance competencies over .internet however no longer as lots as IBM pretended in their paper. besides that, Microsoft remarked that IBM didn't comment on core-tier cost comparison which vastly favors Microsoft.

    Microsoft persisted to problem IBM to

    meet us [Microsoft] in an independent lab to operate extra checking out of the .web StockTrader and WSTest benchmark workloads and pricing evaluation of the core tier application servers established in their benchmark report. additionally, they invite the IBM competitive response group to their lab in Redmond, for dialogue and extra testing in their presence and beneath their review.

    remaining Conclusion

    generally, a benchmark consists of

  • a workload
  • a set of suggestions describing how the workload is to be processed – run guidelines -
  • a procedure making an attempt to make certain that the run suggestions are revered and outcomes are interpreted appropriately
  • A benchmark is constantly supposed to evaluate two or greater methods in order to examine which one is improved for performing certain projects. Benchmarks are additionally used via corporations to increase their hardware/utility before it goes to their customers through checking out diverse tuning parameters and measuring the consequences or through recognizing some bottlenecks. Benchmarks can also be used for advertising and marketing applications, to show that a undeniable gadget has more desirable efficiency than the competitor’s.

    in the beginning, benchmarks had been used to measure the hardware efficiency of a system, just like the CPU processing power. Later, benchmarks have been created to test and evaluate applications like SPEC MAIL2001 and even utility servers like SPECjAppServer2004.

    There is no excellent benchmark. The workload can also be tweaked to desire a certain platform, or the records can be misinterpreted or incorrectly extrapolated. To be convincing, a benchmark needs to be as clear as feasible. The workload definition should still be public, and if feasible the supply code may still be made available for those fascinated to study. a clear set of run guidelines are mandatory so other parties can repeat the same exams to peer the consequences for themselves. the manner consequences are interpreted and their that means need to be disclosed.

    We aren't aware of a response from IBM to Microsoft’s remaining paper. it might be exciting to look their reaction. doubtless, the greatest strategy to clear things up is for IBM to make the source code of their tests public so anybody interested could look at various and spot for themselves where is the actuality. unless then they can most effective speculate on the correctness and validity of these benchmarks.


    IBM tailors BPM for small enterprise

    How collaboration apps foster digital transformation

    IBM boosts business agility in WebSphere middleware upgrade

    seeking to supply business agility, IBM is rolling out on Thursday a slew of items in the edition 7 improve to its WebSphere middleware portfolio.

    available later this 12 months, the products run the gamut from the BPM area to an business service bus and a hardware-based mostly messaging equipment. The rollout specializes in what the company calls the SOA, BPM, and business approach layers for IT.

    [ Also this week, Tibco upgraded its BPM platform, offering business intelligence capabilities. ]

    “What we’ve carried out is they have invested [in] and are releasing at the same time as the edition 7 of their portfolio it's aligned to deliver about the price of enterprise agility,” during the three layers, stated Craig Hayman, customary manager of WebSphere at IBM.

    IBM with its WebSphere release is incorporating agile building practices, noted Brad Shimmin, primary analyst for application infrastructure at current evaluation. “They’re able to more desirable liberate aspects the users need in a more well timed method,” Shimmin mentioned.

    The WebSphere BPM suite is being geared up with a local container as part of the platform’s SCA (carrier element architecture) capabilities. With this container, clients can take the definition of a enterprise process and switch it into an executing equipment in a single click on, Hayman mentioned. SCA, Shimmin referred to, makes it possible for IBM to make its utility more modular.

    additionally featured is “in-flight” alternate management for company strategies. “You’ll be in a position to regulate that company process because it is executing,” mentioned Hayman.

    built-in governance and policy administration is featured in the BPM suite to enhanced bridge the conversation between company and IT leaders, he referred to.

    IBM additionally has superior its cloud-based mostly BPM BlueWorks ambiance for knowing company administration. “we've more suitable the prebuilt industry content,” including skill and manner maps across lots of industries, observed Hayman.  BlueWorks allows for for testing new and existing processes via modeling them in a cloud atmosphere.

    The version 7 WebSphere rollout, which features with the WebSphere 7 software server brought closing 12 months, also includes IBM WebSphere Ilog JRules 7.0, for managing company rules. Capabilities are featured for automating choices in mainframe functions.

    IBM bought Ilog ultimate 12 months. “we have now integrated Ilog with their edition 7 free up,” Hayman said.

    WebSphere procedure Server v7, which is the engine inner IBM’s BPM stack, is being delivered to provide specifications-based process options with capabilities for administering human workflow strategies. presenting for built-in governance and coverage management is WebSphere Registry and Repository and superior Lifecycle version v7. It boosts company/IT recognition with interface and analysis equipment and offers a view of services with federated have an impact on evaluation and alter management, IBM pointed out.

    one other a part of the rollout, WebSphere enterprise events and severe Scale v7, allows for responses to high-volume, true-time pursuits, including hobbies from business functions.

    WebSphere vs. .NET: IBM and Microsoft Go Head to Head

    After carrying out a number of benchmarks, Microsoft concluded that .NET offers better performance and cost-performance ratio than WebSphere. IBM rebutted Microsoft’s findings and carried out other tests proving that WebSphere is superior to .NET. Microsoft responded by rejecting some of IBM’s claims as false and repeating the tests on different hardware with different results.

    Summary

    Microsoft has benchmarked .NET and WebSphere and published the benchmark source code, run rules, use rules and a findings report published at wholoveswindows.com entitled Benchmarking IBM WebSphere 7 on IBM Power6 and AIX vs. Microsoft .NET on HP BladeSystem and Windows Server 2008.   This benchmark shows a much higher transactions per second (TPS) rate and better cost/performance ratio when using WebSphere 7 on Windows Server 2008 over WebSphere on AIX 5.3, and even better results when using .NET on Windows Server 2008 over WebSphere on the same OS. The cost/performance ratio for the application benchmark used is:

    IBM Power 570 with WebSphere 7 and AIX 5.3 HP BladeSystem C7000 with WebSphere 7 and Windows Server 2008 HP BladeSystem C7000 with .NET and Windows Server 2008 $32.45 $7.92 $3.99

    IBM has rebutted Microsoft’s benchmark and called some of their claims as false, and performed a different benchmark, with different results. The benchmark used along with the findings were published in Benchmarking AND BEATING Microsoft’s .NET 3.5 with WebSphere 7! (PDF). The source code of the benchmark was not published. The results show WebSphere as a better performing middle-tier than .NET with 36% more TPS for one application benchmark and from 176% to 450% better throughput for one of IBM’s standard benchmarks.

    Microsoft responded to IBM and defended their claims and benchmarking results with Response to IBM’s Whitepaper Entitled Benchmarking and Beating Microsoft .NET 3.5 with WebSphere 7 (PDF). Microsoft has also re-run their benchmark, modified to include a different test flow similar to the one used by IBM in their tests, running it on different hardware, a single multi-core server, founding that indeed WebSphere is better than .NET if using IBM’s test flow but only slightly better, between 3% and %6, not as reported by IBM. Besides that, these later findings do not change the original ones since the benchmark was run on a different hardware configuration. In the end, Microsoft invites IBM to “an independent lab to perform additional testing”.

    Microsoft Testing .NET Against WebSphere

    Microsoft has conducted a series of tests comparing WebSphere/Java against .NET on three different platforms. The details of the benchmarks performed and the test results were published in the whitepaper entitled Benchmarking IBM WebSphere® 7 on IBM® Power6™ and AIX vs. Microsoft® .NET on Hewlett Packard BladeSystem and Windows Server® 2008 (PDF).

    Platforms tested:

  • IBM Power 570 (Power 6) running IBM WebSphere 7 on AIX 5.3
  • 8 IBM Power6 cores at 4.2GHz
  • 32 GB RAM
  • AIX 5.3
  • 4 x 1 GB NICs
  • Hewlett Packard BladeSystem C7000 running IBM WebSphere 7 on Windows Server 2008
  • 4 Hewlett Packard ProLiant BL460c blades
  • One Quad-Core Intel® Xeon® E5450 (3.00GHz, 1333MHz FSB, 80W) Processor/blade
  • 32 GB RAM/blade
  • Windows Server 2008/64-bit/blade
  • 2 x 1 GB NICs/blade
  • Hewlett Packard BladeSystem C7000 running .NET on Windows Server 2008
  • Same as the previous one but the applications tested run on .NET instead of WebSphere.
  • A number of three tests were performed on each platform:

  • Trade Web Application Benchmarking The applications tested were IBM’s Trade 6.1 and Microsoft’s StockTrader 2.04. This series of tests have evaluated the performance of complete data-driven web applications running on top of the above mentioned platforms. The web pages accessed had one or usually more operations serviced by classes contained by the business layer and ending with synchronous database calls.
  • Trade Middle Tier Web Services Benchmarking This benchmark was intended to measure the performance of the Web Service layer executing operations which ended up in database transactions. The test was similar to Web Application, but operations were counted individually.
  • WS Test Web Services Benchmarking This test was like the previous one but there was no business logic nor database access. This was based on WSTest workload initially devised by Sun and augmented by Microsoft. The services tier offered 3 operations: EchoList, EchoStruct and GetOrder. Having no business logic, the test measured only the raw performance of the Web Service software.
  • Two database configurations were used, one for the all-IBM platform and another for the other two: IBM DB2 V9.5 Enterprise Edition with IBM DB2 V9.5 JDBC drivers for data access and SQL Server 2008 databases Enterprise Edition. Two databases were set up for each configuration running on HP BL680c G5 blades:

  • 4 Quad-Core Intel XEON CPUs, @2.4GHZ (16 cores in each blade)
  • 64 GB RAM
  • 4 x 1GB NICs
  • IBM DB 9.5 Enterprise Edition 64-bit or Microsoft SQL Server 2008 64-bit
  • Microsoft Windows Server 2008 64-bit, Enterprise Edition
  • 2 4GB HBAs for fiber/sans access to the EVA 4400 storage
  • The storage was secured on HP StorageWorks EVA 4400 Disk Array:

  • 96 15K drives total
  • 4 logical volumes consisting of 24 drives each
  • Database server 1: Logical Volume 1 for logging
  • Database server 1: Logical Volume 2 for database
  • Database server 2: Logical Volume 3 for logging
  • Database server 2: Logical Volume 4 for database
  • The Web Application benchmark used 32 client machines running test scripts. Each machine simulated hundreds of clients having a 1 second think time. The tests used an adapted version of IBM’s Trade 6.1 application on SUT #1 & #2 and Microsoft’s StockTrader application on SUT #3.

    image

    For the Web Service and WSTest benchmarks, Microsoft used 10 clients with a 0.1s think time. For WSTest, the databases were not accessed. Microsoft has created a WSTest-compliant benchmark for WebSphere 7 and JAX-WS and another in C# for .NET using WCF.

    image

    Microsoft’s whitepaper contains more details on how the tests were conducted including the DB configuration, DB access used, caching configuration, test scripts, tuning parameters used and others.

    Conclusion

    The benchmarking results including the costs/performance ratio are shown in the following table:

      IBM Power 570 with WebSphere 7 and AIX 5.3 HP BladeSystem C7000 with WebSphere 7 and Windows Server 2008 HP BladeSystem C7000 with .NET and Windows Server 2008 Total Middle-Tier System Cost $260,128.08 $87,161.00 $50,161.00 Trade Web Application Benchmark 8,016 TPS 11,004 TPS 12,576 TPS Cost/Performance $32.45 $7.92 $3.99 Trade Middle Tier Web Service Benchmark 10,571 TPS 14,468 TPS 22,262 TPS Cost/Performance $24.61 $6.02 $2.25 WSTest EchoList Test 10,536 TPS 15,973 TPS 22,291 TPS Cost/Performance $24.69 $5.46 $2.25 WSTest EchoStruct Test 11,378 TPS 16,225 TPS 24,951 TPS Cost/Performance $22.86 $5.37 $2.01 WSTest GetOrder Test 11,009 TPS 15,491 TPS 27,796 TPS Cost/Performance $23.63 $5.63 $1.80

    According to Microsoft’s benchmarking results, running WebSphere on HP BladeSystem with Windows Server 2008 is about 30% more efficient and the cost-performance ratio is 5 times lower than running WebSphere on IBM Power 570 with AIX 5.3. The .NET/Windows Server 2008 configuration is even more efficient and the cost/performance ratio drops to half compared to WebSphere/Windows Server 2008 and it is 10 times smaller than WebSphere/Power 570/AIX. The cost-performance ratio is so high for the first platform because the price of the entire middle-tier is over $250,000 while the performance is lower than the other platforms.

    Microsoft’s benchmarking whitepaper (PDF) contains an appendix with complete details of the hardware and software costs. The benchmarking tests used, including source code, are published on StockTrader website.

    IBM’s Rebuttal

    In another paper, Benchmarking AND BEATING Microsoft’s .NET 3.5 with WebSphere 7! (PDF), IBM has rejected Microsoft’s benchmark and created another one showing that WebSphere is performing better than .NET.

    Microsoft had said that StockTrader is similar to IBM’s Trade application:

    Microsoft created an application that is functionally equivalent to the IBM WebSphere Trade application, both in terms of user functionality and middle-tier database access, transactional and messaging behavior.

    IBM rejected Microsoft’s claim:

    The application claims to be “functionally equivalent” to the IBM WebSphere Trade 6.1 sample application. It is not a “port” of the application in any sense. Little, if any, of the original application design was ported. Microsoft has made this an application that showcases the use of its proprietary technologies. A major indication of this is the fact that the .NET StockTrader application is not a universally accessible web application since it can only be accessed by using Internet Explorer, and not by other web browsers.

    Furthermore, IBM said that Trade was not designed to benchmark WebSphere’s performance but rather to

    serve as a sample application illustrating the usage of the features and functions contained in WebSphere and how they related to application performance. In addition, the application served as a sample which allowed developers to explore the tuning capabilities of WebSphere.

    IBM had other complaints regarding Microsoft’s benchmark:

    Microsoft created a completely new application [StockTrader] and claimed functional equivalence at the application level. The reality is that the Microsoft version of the application used proprietary SQL statements to access the database, unlike the original version of Trade 6.1 which was designed to be a portable and generic application.

    They employed client side scripting to shift some of the application function to the client.

    They tested Web Services capabilities by inserting an unnecessary HTTP server between the WebSphere server and the client.

    And If that was not enough, they failed to properly monitor and adjust the WebSphere application server to achieve peak performance.

    IBM’s Competitive Project Office team (CPO) has ported StockTrader 2.0 to WebSphere creating CPO StockTrader and claiming: “we did a port that faithfully reproduced Microsoft’s application design. The intent was to achieve an apples-to-apples comparison.” So, Trader 6.1 was ported by Microsoft from WebSphere to .NET under the name StockTrader and ported again by IBM back to WebSphere under the name CPO StockTrader. IBM benchmarked CPO StockTrader against StockTrader and obtained better results for WebSphere against .NET:

    image

    IBM has also informed they are using Friendly Bank, an application intended to benchmark WebSphere against .NET. In this test WebSphere outperforms .NET several times:

    image

    In their StockTrader vs. CPO StockTrader benchmark, IBM used scripts simulating user activity: “login, getting quotes, stock buy, stock sell, viewing of the account portfolio, then a logoff” and running in stress mode without think times. 36 users were simulated, enough to drive each server at maximum throughput and utilization. The data returned was validated and errors were discarded.

    The front end was implemented with WebSphere 7/Windows Server 2008 in one case and .NET 3.5 with IIS 7/Windows Server 2008 in the other. The back end database was DB2 8.2 and SQL Server 2005, both on Windows Server 2003.

    The hardware used for testing was:

    Performance Testing Tool HardwareX345 8676 Server2 X 3.06 GHz Intel Processor with Hyper Thread Technology8 GB RAM18.2 GB 15K rpm SCSC Hard Disk Drive1 GB Ethernet interfaceApplication Server Hardware IBM X3950 Server, 8 x 3.50 Ghz, Intel Xeon Processors with Hyper Thread Technology, 64 GB RAMDatabase Server HardwareX445 8670 Server, 8x 3.0 Ghz. Intel Xeon Processors with Hyper Thread Technology, 16 GB RAMUltraSCSI 320 Controller , EXP 300 SCSI Expansion Unit, 14x 18.2 GB 15K rpm Hard Disk Drive configured as 2 Raid Arrays.One for Logs & One for Database, Each array is comprised of 7 hard disks in a Raid 0 configuration.The Ethernet Network Backbone The isolated network hardware is comprised of 3x 3Comm SuperStack 4950 switches and one 3 Comm SuperStack 4924 switch running at 1 GB.

    The software and hardware configuration for the Friendly Bank benchmark was similar to the StockTrader one.

    IBM’s whitepaper contains information about the Friendly Bank application, but does not point to the source code. It also mentions that the application was initially designed for .NET Framework 1.1 and was just recompiled on .NET 3.5 without being updated to use the latest technologies.

    Microsoft Response to IBM’s Rebuttal

    Microsoft has responded to IBM’s rebuttal in yet another whitepaper, Response to IBM’s Whitepaper Entitled Benchmarking and Beating Microsoft .NET 3.5 with WebSphere 7 (PDF). In this document, Microsoft defends their original benchmarking results and affirms that IBM made some false claims in their rebuttal document entitled Benchmarking AND BEATING Microsoft’s .NET 3.5 with WebSphere 7!, and IBM failed to use an appropriate benchmarking procedure.  More has been posted at wholoveswindows.com.

    Basically, Microsoft said the following claims are false:

  • IBM claim: The .NET StockTrader does not faithfully reproduce the IBM Trade application functionality.Microsoft response: this claim is false; the .NET StockTrader 2.04 faithfully reproduces the IBM WebSphere Trade application (using standard .NET Framework technologies and coding practices), and can be used for fair benchmark comparisons between .NET 3.5 and IBM WebSphere 7.
  • IBM claim: The .NET StockTrader uses client-side script to shift processing from the server to the client.Microsoft response: this claim is false, there is no client-side scripting in the .NET StockTrader application.
  • IBM claim: The .NET StockTrader uses proprietary SQL.Microsoft response: the .NET StockTrader uses typical SQL statements coded for SQL Server and/or Oracle; and provides a data access layer for both. The IBM WebSphere 7 Trade application similarly uses JDBC queries coded for DB2 and/or Oracle. Neither implementation uses stored procedures or functions; all business logic runs in the application server. Simple pre-prepared SQL statements are used in both applications.
  • IBM claim: The .NET StockTrader is not programmed as a universally accessible, thin-client Web application. Hence it runs only on IE, not in Firefox or other browsers.Microsoft response: In reality, the .NET StockTrader Web tier is programmed as a universally accessible, pure thin client Web application. However, a simple issue in theuse of HTML comment tags causes issues in Firefox; these comment tags are being updated to allow the ASP.NET application to properly render in any industry standard browser, including Firefox.
  • IBM claim: The .NET StockTrader has errors under load.Microsoft response: This is false, and this document includes further benchmark tests and Mercury LoadRunner details proving this IBM claim to be false.
  • Also, Microsoft complained that IBM had developed Friendly Bank for .NET Framework 1.1 years ago using obsolete technologies:

    IBM’s Friendly Bank benchmark uses an obsolete .NET Framework 1.1 application that includes technologies such as DCOM that have been obsolete for many years. This benchmark should be fully discounted until Microsoft has the chance to review the code and update it for .NET 3.5, with newer technologies for ASP.NET, transactions, and Windows Communication Foundation (WCF) TCP/IP binary remoting (which replaced DCOM as the preferred remoting technology).

    Microsoft considered IBM failed by not providing the source code for CPO StockTrader and Friendly Bank applications and reiterated the fact that all the source code for Microsoft’s benchmark applications involved in this case had been made public.

    Microsoft also noticed that IBM had used a modified test script which “included a heavier emphasis on buys and also included a sell operation”. Microsoft re-performed their benchmark using IBM’s modified test script flow, one including the operations Buy and Sell beside Login, Portfolio, Logout, on a single 4-core application server affirming that

    these tests are based on IBM’s revised script and are meant to satisfy some of these IBM rebuttal test cases as outlined in IBM’s response paper. They should not be considered in any way as a change to their original results (performed on different hardware, and different test script flow); as the original results remain valid.

    The test was carried on:

    Application Server(s) Database(s) 1 HP ProLiant BL460c1 Quad-core Intel Xeon E5450 CPU (3.00 GHz)32 GB RAM2 x 1GB NICsWindows Server 2008 64-bit.NET 3.5 (SP1) 64-bitIBM WebSphere 64-bit 1 HP ProLiant DL380 G52 Quad-core Intel Xeon E5355 CPUs (2.67 GHz)64 GB RAM2 x 1GB NICsWindows Server 2008 64-bitSQL Server 2008 64-bitDB2 V9.7 64-bit

    The result of the test shows similar performance for WebSphere and .NET.

    image

    One of IBM’s complaints had been that Microsoft inserted an unnecessary HTTP web server in front of WebSphere reducing the number of transactions per second. Microsoft admitted that, but added:

    The use of this HTTP Server was fully discussed in the original benchmark paper, and is done in accordance with IBM’s own best practice deployment guidelines for WebSphere. In such a setup, IBM recommends using the IBM HTTP Server (Apache) as the front end Web Server, which then routes requests to the IBM WebSphere Application server. In their tests, they co-located this HTTP on the same machine as the Application Server. This is equivalent to the .NET/WCF Web Service tests, where they hosted the WCF Web Services in IIS 7, with co-located IIS 7 HTTP Server routing requests to the .NET application pool processing the WCF service operations. So in both tests, they tested an equivalent setup, using IBM HTTP Server (Apache) as the front end to WebSphere/JAX-WS services; and Microsoft IIS 7 as the front end to the .NET/WCF services. Therefore, they stand behind all their original results.

    Microsoft performed yet another test, the WSTest, without the intermediary HTTP web server on a single quad-core server like the previous one, and obtained the following result:

    Both tests performed by Microsoft on a single server show WebSphere holding a slight performance advantage over .NET but not as much as IBM pretended in their paper. Besides that, Microsoft remarked that IBM did not comment on middle-tier cost comparison which greatly favors Microsoft.

    Microsoft continued to challenge IBM to

    meet us [Microsoft] in an independent lab to perform additional testing of the .NET StockTrader and WSTest benchmark workloads and pricing analysis of the middle tier application servers tested in their benchmark report. In addition, they invite the IBM competitive response team to their lab in Redmond, for discussion and additional testing in their presence and under their review.

    Final Conclusion

    Generally, a benchmark consists of

  • a workload
  • a set of rules describing how the workload is to be processed – run rules -
  • a process trying to ensure that the run rules are respected and results are interpreted correctly
  • A benchmark is usually intended to compare two or more systems in order to determine which one is better for performing certain tasks. Benchmarks are also used by companies to improve their hardware/software before it goes to their customers by testing different tuning parameters and measuring the results or by spotting some bottlenecks. Benchmarks can also be used for marketing purposes, to prove that a certain system has better performance than the competitor’s.

    In the beginning, benchmarks were used to measure the hardware performance of a system, like the CPU processing power. Later, benchmarks were created to test and compare applications like SPEC MAIL2001 and even application servers like SPECjAppServer2004.

    There is no perfect benchmark. The workload can be tweaked to favor a certain platform, or the data can be misinterpreted or incorrectly extrapolated. To be convincing, a benchmark needs to be as transparent as possible. The workload definition should be public, and if possible the source code should be made available for those interested to look at. A clear set of run rules are mandatory so other parties can repeat the same tests to see the results for themselves. The way results are interpreted and their meaning must be disclosed.

    We are not aware of a response from IBM to Microsoft’s last paper. It would be interesting to see their reaction. Probably, the best way to clear things up is for IBM to make the source code of their tests public so anybody interested could test and see for themselves where is the truth. Until then they can only speculate on the correctness and validity of these benchmarks.
