Anton, one thing you should probably do is put your min heap size to the same as your max (-Xms512m) because you could be running into a lot of garbage collection issues. Also, what version of Java are you running, 1.4 or 1.5? As for the CPU, it should not be doing much when jetspeed is idle and not being hit. So if it is, then you definitely have a problem. Memory might be the main culprit though. Before setting your heap size to a fixed one, you should note if the java process moves up to the 512 max quickly and stays around there. If so, that could mean that you should crank it higher, maybe around 768. Anyway, I certainly hope that this is not typical! I don't know as I haven't gotten that far yet.
