[jboss-user] [Performance Tuning] - Re: Diff response times at different times

Thanks Peter For your excellent support. During the load test run, I saw that the CPU utilization is around 60-70% I'm setting the PermGen Size to 512m with the params -XX:PermSize=64m -XX:MaxPermSize=512m If I donot set this, I'm quickly getting Out of Memory Permgen Space Error. If I can't

I tried with the below JVM Settings : set JAVA_OPTS=%JAVA_OPTS% -Xms1024m –Xmx1024m –XX:NewSize=300M –XX:MaxNewSize=300M –XX:SurvivorRatio=32 –XX:+UseTLAB –XX:TLABSize=64K But this settings didn't work well for me. With this setting, I observed that the response time is increased
