[jboss-user] [Performance Tuning] - Re: High CPU consumption.

[lafr]

You set the MaxPermSize but not the starting value: add "-XX:NewSize=128m" to the parameter list.
Don't know much about the flags "-XX:+UseParNewGC" and "-XX:+CMSParallelRemarkEnabled" and JBoss on Linux, but I would try to run without it.
JDK 1.5 checks the system for available CPUs and memory and set's values based on that.

You also may add "-verbose:gc -XX:+PrintGCDetails -XX:+PrintGCTimeStamps -XX:-TraceClassUnloading" to see GC messages and see if there are messages generated constantly when the CPU load increases.
