are you sure that tomcat is your bottleneck? Your 4 CPU machine (which cpu's btw?) should be able to handle more than 1000 users (unless you are speaking about suns cpu) without problems. Maybe you should provide more info about your application. Do you have any monitoring data?

Hello, I was hoping somebody on the list might point me in the right direction... I am trying to scale up Tomcat based web application currently supporting ~100 users to 350 users. It seems that I have enough hardware: 2 load balanced servers x 4 CPUs each with 4 GB of RAM which is underutilized for most of the time even though application performance slows dramatically at peak times. I was advised to install multiple JVMs in order to improve Tomcat's performance. Another option I considered was to install 2 instances of Tomcat on each server to see whether it would handle increased load. Would anybody know what kind of performance improvement would multiple JVM/Tomcat installations provide? Are there any benchmarks available? Thank you for any help!
