JSP Compilation on multicore machines (JRockit & HotSpot)
Hi,
I am investigating some issues my customer has with (pre-)compiling his JSP-webApp with weblogic.appc. We have not pinpointed the problem yet, but boils down to this : the number of cores can have a serious impact on the behaviour and the results of the compilation, in JRockit and HotSpot... when running in Oracle VM
When we try JR4 or JDK6 on an "12 core - 32Gb" system (VM), the compilation end 1 out of 3 on an exception (more about the exception lateron)
When we try JR4 or JDK6 on an "4 core - 12 Gb" system (VM), the compilation ends flawlessly and faster !!! (20 % : from 38 min to 24 min)
