Subject Tomcat's scalability
Date Mon, 19 Jun 2006 17:34:49 GMT
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!
