to add to this - the amount of memory required for each session is going 
to depend entirely on what your applications are putting in client 
session scopes. How much information you put in a session and how much 
traffic your site(s) receive will have an impact on your memory 
requirements. Also worth noting is that all of your JRun instances share 
a JVM.config file by default - I recommend profiling your application 
usage and creating seperate JVM config files for each instance - this 
will help you control memory allocation (for the JVM Heap) as needed.
