In response to: Oracle's True Lies with SPECjAppServer@Alex, regardless of why Oracle chose to compare the RISC and CISC platforms, the result is not meaningless. Java App Servers are licensed on cores that they run on. For most companies, bang for buck is a key measure. As the comparison is JEE compliant Java App Servers, we can legitimately compare app servers running on different underlying hardware architectures and come up with a legitimate measure of bang for buck.
Let's look at IBM's and Oracle's licensing for this benchmark; the WebLogic instance would require 24 CPU equivalent*** (48 x 0.5) licenses of Weblogic App Server (Enterprise Edition) while the Power system will require 480 Processor Value Units (4x120) of WebSphere Application Server Network Deployment. To compare the two models if we take the list price for WebLogic Enterprise Edition (US$30,500* per CPU equivalent) and IBM's WebSphere App Server ND (US$174/PVU*) then we see that the Oracle WebLogic App Server license (US$732,000) will cost 776% more than the IBM WebSphere App Server license (US$83,520).
Oracle are claiming "...nearly 7 times..." the performance despite the fact that 9,455.17/1,197.51 = 7.90 (to 2 decimal places) which in my book is nearly 8 times the performance, not nearly 7 times. I think their marketing people got their percentages mixed up - 7.90 times the performance of the IBM score is a 690% improvement on the IBM score.
So, let's give them the benefit of the doubt and assume the Oracle marketing folks made a mistake and their benchmark system can deliver 7.9 times the performance of the IBM benchmark system, they are doing it for 8.7 times the price of the IBM system in terms of app server licensing, that is not looking like the spectacular win that Oracle are claiming it to be... In the bang for buck war (at least in software licenses), IBM still wins.
