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 increase the heapsize beyond 1700MB(including permgen),
Does that mean 2GB/4GB/8GB RAM will not make much difference?
If garbage collector is not the culprit for the difference in response times at different intervals, I wonder what else could be the reason...?
Will clustering of JBoss help me in meeting the SLA?
If yes, can I try the software clustering(with out adding any other hardware), or I have to go with Hardware Clustering only?
