IBM DB2 techniques
After engaging in a number of benchmarks, Microsoft concluded that .web offers enhanced efficiency and value-performance ratio than WebSphere. IBM rebutted Microsoft’s findings and performed different checks proving that WebSphere is superior to .web. Microsoft replied with the aid of rejecting a few of IBM’s claims as false and repeating the tests on diverse hardware with different consequences.
summary
Microsoft has benchmarked .net and WebSphere and posted the benchmark source code, run guidelines, use guidelines and a findings file posted at wholoveswindows.com entitled Benchmarking IBM WebSphere 7 on IBM Power6 and AIX vs. Microsoft .internet on HP BladeSystem and windows Server 2008. This benchmark suggests a a great deal larger transactions per 2nd (TPS) expense and enhanced can charge/efficiency ratio when the usage of WebSphere 7 on home windows Server 2008 over WebSphere on AIX 5.3, and even better effects when using .internet on home windows Server 2008 over WebSphere on the identical OS. The charge/performance ratio for the application benchmark used is:
IBM power 570 with WebSphere 7 and AIX 5.3

IBM has rebutted Microsoft’s benchmark and known as some of their claims as false, and performed a distinct benchmark, with different results. The benchmark used together with the findings have been published in Benchmarking AND BEATING Microsoft’s .net three.5 with WebSphere 7! (PDF). The supply code of the benchmark changed into not published. The effects reveal WebSphere as a far better performing core-tier than .web with 36% more TPS for one application benchmark and from 176% to 450% superior throughput for certainly one of IBM’s common benchmarks.
Microsoft spoke back to IBM and defended their claims and benchmarking results with Response to IBM’s Whitepaper Entitled Benchmarking and Beating Microsoft .net three.5 with WebSphere 7 (PDF). Microsoft has also re-run their benchmark, modified to include a special test move corresponding to the one used with the aid of IBM in their exams, operating it on different hardware, a single multi-core server, founding that certainly WebSphere is better than .web if using IBM’s look at various move but handiest just a little more desirable, between three% and %6, now not as pronounced by means of IBM. anyway that, these later findings do not change the customary ones on account that the benchmark changed into run on a different hardware configuration. within the conclusion, Microsoft invitations IBM to “an unbiased lab to operate additional checking out”.
Microsoft trying out .internet towards WebSphere
Microsoft has conducted a sequence of tests comparing WebSphere/Java against .internet on three distinctive platforms. The particulars of the benchmarks performed and the check consequences have been published in the whitepaper entitled Benchmarking IBM WebSphere® 7 on IBM® Power6™ and AIX vs. Microsoft® .internet on Hewlett Packard BladeSystem and home windows Server® 2008 (PDF).

same because the old one however the applications confirmed run on .web as an alternative of WebSphere.
a couple of three assessments have been carried out on each platform:
change internet application Benchmarking The functions confirmed have been IBM’s exchange 6.1 and Microsoft’s StockTrader 2.04. This series of exams have evaluated the performance of complete facts-driven internet functions running on desirable of the above mentioned platforms. The web pages accessed had one or constantly extra operations serviced by classes contained with the aid of the enterprise layer and ending with synchronous database calls.
trade core Tier net capabilities Benchmarking This benchmark changed into supposed to measure the efficiency of the web service layer executing operations which ended up in database transactions. The check become similar to internet application, however operations were counted in my view.
WS test web services Benchmarking This test become just like the old one however there was no enterprise common sense nor database entry. This became in keeping with WSTest workload firstly devised via solar and augmented by way of Microsoft. The services tier offered three operations: EchoList, EchoStruct and GetOrder. Having no enterprise logic, the look at various measured handiest the raw performance of the net carrier software.
Two database configurations were used, one for the all-IBM platform and yet another for the other two: IBM DB2 V9.5 commercial enterprise edition with IBM DB2 V9.5 JDBC drivers for information access and SQL Server 2008 databases business version. Two databases have been installation for every configuration running on HP BL680c G5 blades:
4 Quad-Core Intel XEON CPUs, @2.4GHZ (16 cores in each blade)
sixty four GB RAM
4 x 1GB NICs
IBM DB 9.5 commercial enterprise version 64-bit or Microsoft SQL Server 2008 sixty four-bit
Microsoft windows Server 2008 sixty four-bit, commercial enterprise edition

The storage changed into secured on HP StorageWorks EVA 4400 Disk Array:
ninety six 15K drives complete
four logical volumes consisting of 24 drives each
Database server 1: Logical quantity 1 for logging
Database server 1: Logical volume 2 for database
Database server 2: Logical volume three for logging
Database server 2: Logical quantity 4 for database
The net application benchmark used 32 client machines operating test scripts. every laptop simulated a whole bunch of customers having a 1 2d consider time. The exams used an adapted version of IBM’s alternate 6.1 software on SUT #1 & #2 and Microsoft’s StockTrader utility on SUT #3.
For the internet carrier and WSTest benchmarks, Microsoft used 10 shoppers with a 0.1s feel time. For WSTest, the databases were now not accessed. Microsoft has created a WSTest-compliant benchmark for WebSphere 7 and JAX-WS and an extra in C# for .net the usage of WCF.
Microsoft’s whitepaper consists of extra particulars on how the checks have been carried out including the DB configuration, DB access used, caching configuration, look at various scripts, tuning parameters used and others.
Conclusion
The benchmarking effects together with the fees/performance ratio are proven in here table:

in line with Microsoft’s benchmarking consequences, working WebSphere on HP BladeSystem with home windows Server 2008 is set 30% more efficient and the cost-efficiency ratio is 5 times lower than working WebSphere on IBM vigour 570 with AIX 5.3. The .internet/home windows Server 2008 configuration is much more efficient and the can charge/performance ratio drops to half compared to WebSphere/windows Server 2008 and it is 10 instances smaller than WebSphere/vigour 570/AIX. The cost-efficiency ratio is so excessive for the first platform because the rate of the total middle-tier is over $250,000 whereas the efficiency is reduce than the different platforms.
Microsoft’s benchmarking whitepaper (PDF) includes an appendix with finished details of the hardware and application prices. The benchmarking tests used, together with supply code, are posted on StockTrader site.
IBM’s Rebuttal
In a different paper, Benchmarking AND BEATING Microsoft’s .net three.5 with WebSphere 7! (PDF), IBM has rejected Microsoft’s benchmark and created one other one displaying that WebSphere is performing better than .web.
Microsoft had mentioned that StockTrader is akin to IBM’s alternate software:
Microsoft created an software it truly is functionally such as the IBM WebSphere change software, each in terms of user functionality and center-tier database entry, transactional and messaging conduct.
IBM rejected Microsoft’s claim:
The utility claims to be “functionally equal” to the IBM WebSphere exchange 6.1 pattern software. It is not a “port” of the application in any sense. Little, if any, of the long-established software design was ported. Microsoft has made this an software that showcases using its proprietary technologies. a major indication of here is the proven fact that the .internet StockTrader software isn't a universally available net utility given that it may handiest be accessed through the use of internet Explorer, and never through different internet browsers.
in addition, IBM stated that change become no longer designed to benchmark WebSphere’s performance but somewhat to
serve as a trial
application illustrating the utilization of the aspects and capabilities contained in WebSphere and the way they regarding utility performance. additionally, the application served as a trial
which allowed builders to explore the tuning capabilities of WebSphere.
IBM had other complaints involving Microsoft’s benchmark:
Microsoft created a very new utility [StockTrader] and claimed practical equivalence on the utility stage. The fact is that the Microsoft version of the software used proprietary SQL statements to access the database, unlike the normal version of trade 6.1 which became designed to be a portable and customary utility.
They employed client facet scripting to shift one of the software characteristic to the client.
They validated internet capabilities capabilities through inserting an pointless HTTP server between the WebSphere server and the client.
And If that changed into now not sufficient, they didn't effectively computer screen and adjust the WebSphere software server to achieve height efficiency.
IBM’s aggressive mission office team (CPO) has ported StockTrader 2.0 to WebSphere developing CPO StockTrader and claiming: “we did a port that faithfully reproduced Microsoft’s application design. The intent became to obtain an apples-to-apples evaluation.” So, dealer 6.1 turned into ported via Microsoft from WebSphere to .internet below the name StockTrader and ported once again through IBM back to WebSphere below the identify CPO StockTrader. IBM benchmarked CPO StockTrader in opposition t StockTrader and bought stronger results for WebSphere in opposition t .net:
IBM has also advised they are the use of friendly bank, an software intended to benchmark WebSphere towards .internet. during this verify WebSphere outperforms .web a number of instances:
in their StockTrader vs. CPO StockTrader benchmark, IBM used scripts simulating consumer pastime: “login, getting costs, stock buy, inventory promote, viewing of the account portfolio, then a logoff” and operating in stress mode without suppose instances. 36 users had been simulated, sufficient to force each and every server at highest throughput and utilization. The facts lower back was validated and errors have been discarded.
The entrance end turned into carried out with WebSphere 7/windows Server 2008 in one case and .net 3.5 with IIS 7/home windows Server 2008 within the different. The again conclusion database changed into DB2 8.2 and SQL Server 2005, both on home windows Server 2003.
The hardware used for checking out became:

The application and hardware configuration for the friendly financial institution benchmark become corresponding to the StockTrader one.
IBM’s whitepaper consists of information about the pleasant financial institution software, but does not aspect to the source code. It also mentions that the application was in the beginning designed for .internet Framework 1.1 and turned into simply recompiled on .net 3.5 with out being up to date to make use of the latest technologies.
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 .internet three.5 with WebSphere 7 (PDF). in this document, Microsoft defends their usual benchmarking consequences and affirms that IBM made some false claims in their rebuttal document entitled Benchmarking AND BEATING Microsoft’s .internet three.5 with WebSphere 7!, and IBM failed to use a suitable benchmarking process. extra has been posted at wholoveswindows.com.
in fact, Microsoft pointed out the following claims are false:
IBM declare: The .internet StockTrader doesn't faithfully reproduce the IBM trade utility performance.Microsoft response: this declare is fake; the .web StockTrader 2.04 faithfully reproduces the IBM WebSphere alternate application (using standard .internet Framework applied sciences and coding practices), and may be used for fair benchmark comparisons between .net 3.5 and IBM WebSphere 7.
IBM declare: The .web StockTrader makes use of customer-side script to shift processing from the server to the client.Microsoft response: this claim is false, there isn't any client-side scripting in the .internet StockTrader utility.
IBM claim: The .internet StockTrader uses proprietary SQL.Microsoft response: the .net StockTrader uses standard SQL statements coded for SQL Server and/or Oracle; and offers an information access layer for each. The IBM WebSphere 7 trade utility similarly uses JDBC queries coded for DB2 and/or Oracle. Neither implementation makes use of kept approaches or functions; all enterprise good judgment runs within the software server. elementary pre-organized SQL statements are utilized in each purposes.
IBM claim: The .net StockTrader isn't programmed as a universally accessible, skinny-customer net software. therefore it runs handiest on IE, now not in Firefox or different browsers.Microsoft response: basically, the .net StockTrader web tier is programmed as a universally accessible, pure thin client internet utility. although, an easy situation in theuse of HTML remark tags motives considerations in Firefox; these remark tags are being up-to-date to allow the ASP.net application to adequately render in any industry usual browser, including Firefox.
IBM declare: The .web StockTrader has mistakes under load.Microsoft response: here's false, and this doc contains extra benchmark exams and Mercury LoadRunner details proving this IBM claim to be false.
also, Microsoft complained that IBM had developed friendly bank for .internet Framework 1.1 years in the past the use of out of date applied sciences:
IBM’s friendly bank benchmark uses an out of date .internet Framework 1.1 application that contains technologies reminiscent of DCOM which have been out of date for many years. This benchmark should still be entirely discounted except Microsoft has the possibility to overview the code and replace it for .internet 3.5, with more exact
technologies for ASP.internet, transactions, and home windows verbal exchange groundwork (WCF) TCP/IP binary remoting (which changed DCOM because the preferred remoting expertise).
Microsoft regarded IBM failed with the aid of not proposing the source code for CPO StockTrader and friendly bank purposes and reiterated the undeniable fact that the entire supply code for Microsoft’s benchmark purposes concerned during this case had been made public.
Microsoft additionally noticed that IBM had used a modified check script which “protected a heavier emphasis on buys and additionally blanketed a sell operation”. Microsoft re-performed their benchmark using IBM’s modified verify script circulate, one including the operations purchase and promote beside Login, Portfolio, Logout, on a single 4-core software server affirming that
these assessments are in response to IBM’s revised script and are supposed to satisfy some of these IBM rebuttal test instances as outlined in IBM’s response paper. They should still now not be regarded in any means as a change to our original outcomes (performed on distinct hardware, and diverse examine script flow); as the common consequences stay valid.
The test become carried on:
application Server(s)
Database(s)

The effect of the verify suggests similar performance for WebSphere and .web.
considered one of IBM’s complaints had been that Microsoft inserted an needless HTTP internet server in front of WebSphere decreasing the variety of transactions per 2d. Microsoft admitted that, but delivered:
the use of this HTTP Server became completely discussed within the common benchmark paper, and is done in line with IBM’s personal top-quality follow deployment guidelines for WebSphere. In one of these setup, IBM recommends the usage of the IBM HTTP Server (Apache) because the entrance conclusion net Server, which then routes requests to the IBM WebSphere application server. In our tests, we co-determined this HTTP on the equal machine because the application Server. here is reminiscent of the .net/WCF web provider checks, the place we hosted the WCF net functions in IIS 7, with co-observed IIS 7 HTTP Server routing requests to the .net utility pool processing the WCF service operations. So in each assessments, we proven an equal setup, the usage of IBM HTTP Server (Apache) as the front conclusion to WebSphere/JAX-WS functions; and Microsoft IIS 7 as the entrance conclusion to the .web/WCF features. therefore, we stand in the back of all our original outcomes.
Microsoft carried out yet one more check, the WSTest, devoid of the intermediary HTTP internet server on a single quad-core server just like the outdated one, and got here influence:
each exams performed by using Microsoft on a single server demonstrate WebSphere conserving a moderate performance advantage over .internet however now not as a good deal as IBM pretended of their paper. anyway that, Microsoft remarked that IBM didn't comment on center-tier cost comparison which vastly favors Microsoft.
Microsoft continued to challenge IBM to
meet us [Microsoft] in an unbiased lab to operate additional testing of the .web StockTrader and WSTest benchmark workloads and pricing analysis of the center tier software servers confirmed in our benchmark report. additionally, we invite the IBM aggressive response group to our lab in Redmond, for dialogue and further trying out of their presence and under their assessment.
last Conclusion
generally, a benchmark contains
a workload
a group of guidelines describing how the workload is to be processed – run rules -
a technique attempting to be sure that the run guidelines are revered and outcomes are interpreted as it should be
A benchmark is constantly intended to compare two or greater methods in an effort to check which one is more advantageous for performing definite projects. Benchmarks are additionally used with the aid of corporations to Excellerate their hardware/application earlier than it goes to their purchasers by using testing distinct tuning parameters and measuring the effects or via spotting some bottlenecks. Benchmarks can also be used for advertising functions, to prove that a definite equipment has better efficiency than the competitor’s.
in the beginning, benchmarks were used to measure the hardware efficiency of a system, just like the CPU processing vigor. Later, benchmarks had been created to verify and evaluate purposes like SPEC MAIL2001 and even utility servers like SPECjAppServer2004.
There is not any ideal benchmark. The workload may also be tweaked to want a certain platform, or the records may also be misinterpreted or incorrectly extrapolated. To be convincing, a benchmark has to be as transparent as viable. The workload definition may still be public, and if feasible the supply code should be made accessible for those involved to examine. a clear set of run suggestions are mandatory so different parties can repeat the equal tests to see the effects for themselves. the style effects are interpreted and their meaning need to be disclosed.
We are not aware about a response from IBM to Microsoft’s ultimate paper. it might be enjoyable to see their response. doubtless, the ideal approach to clear things up is for IBM to make the supply code of their exams public so any one fascinated may check and notice for themselves the place is the certainty. until then we will handiest speculate on the correctness and validity of these benchmarks.
