Take a look at the latest SPECjappserver2004 world record result. Remember BEA's press release a few weeks ago? Take a look here. In that Press release BEA referenced a SPECjappserver2004 result as an example of JRockit's high performance. Hmmmm. The latest SPECjappserver2004 world record is indeed using BEA Weblogic, but its running on Sun Fire X4100's, Solaris 10, and dare I say Sun Hotspot J2SE 5.0_06. Now, JRockit doesn't support Solaris, and the hardware platforms are different, but this result certainly doesn't support BEA's marketing fluff. The reality is that most of BEA's performance messaging is just that, marketing fluff, and the rubber hits the road with the performance of your application in your lab. This is where Hotspot will truely shine. It will be a few more weeks until 5.0_06 is released. In the meantime, take a look at the latest mustang builds on java.net if you curious. Also, visit the performance project and forums on Java.net. We want to here your feedback!
