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
There was a typo in my earlier post regarding CPU Utilization.
It was around 60-90% during peak load

I think I plotted graphs properly this time.
1. When set JAVA_OPTS=%JAVA_OPTS% -Xms1024m -Xmx1024m
Graph is http://img169.imageshack.us/img169/6715/withoutyoung.jpg
2. When set JAVA_OPTS=%JAVA_OPTS% -Xms1024m -Xmx1024m -XX:NewSize=300M
-XX:MaxNewSize=300M -XX:SurvivorRatio=32 -XX:+UseTLAB
Please pardon me for my poor excel skills.
The csv files for the tests are here

2. With Young size setting

What is meant by think time?

I tried with the below JVM Settings :
set JAVA_OPTS=%JAVA_OPTS% -Xms1024m âXmx1024m âXX:NewSize=300M
âXX:MaxNewSize=300M âXX:SurvivorRatio=32 âXX:+UseTLAB âXX:TLABSize=64K
But this settings didn't work well for me.
With this setting, I observed that the response time is increased

As part of slimming the Jboss default server, I have removed couple of things
in jboss\server\default directory without complete knowledge.
After doing that, while trying to shutdown the server by calling
shutdown -S, I'm getting the below error

Thanks Peter for valuable inputs.
