Hi All, Another tip to mention is use of startup options for JBoss. I use the default startup instead of the All option. I did not need the services provided by the All option but I did need EJB support and I found a recommendation a year ago that from the JBoss CTO to reduce resources and improve performance to use the Default option. I measured performance before and after and sure enough he was right. Again if the CPU is occupied providing more services reduction of those services will improve performance.
Also, I forgot to answer one of the good points PeterJ mentioned regarding use of the tenured (old) generation area of the heap. If you do not need the heap space there do not size it too big because the garbage collection takes longer in the tenured area the more space you allocate even if you do not use all of it. I only used 400MB for the heap because my server I was experimenting with only had 1GB. But even if it was a production server I would only size it to what is needed but probably start off with what PeterJ mentioned. Never be afraid to experiment to find the performance sweet point try new things cheaper to do it before production than find out later. Got to go.
