Chips are Intel Xeon. My monitoring data:

It means that you have some network or hard disk issue.
Handling of database with the large data.
The bottom line is that Tomcat/my application combo don't seem to handle
more than a certain number of users. All I want to do is to up the # of
users by 3.
By default it is much more than 3 AFAIK.
So far it sounds that the approach of adding separate instance of Tomcat and
using round robin is better than adding a separate JVM.
Tomcat will run in seperate JVM.
Your problem is NOT in Tomcat. I would site you have typical DB related
problem.
