We have found that after 4 sockets that either you get no additional performance benefit or performance drops. And that some deployed apps run better on 2, others on 3, and others on 4 sockets. Operating System is Windows Server 2k3, sorry forgot to specify that. Where can I grab the heap settings from? Sorry I haven't needed to get that information before. More info on the swapping is that as the amount of users sending their info to the database increases, the server uses more of the swap space. It's almost like it is storing client information, yet the server logically has nobody logged into it. I'll look into the CPU performance problems. Just looking for a solution to make it so that the server can handle more information as our user base is becoming larger. I am assuming right now that JBoss and that server are not functioning properly, as it is quite powerful for what it is doing.
