That's quite good already. If you look at

http://java.sun.com/j2se/1.5.0/docs/...aris/java.html

Look at the documentation for these options, it says Linux platforms are limited to around 2GB, or less. Only SPARC may go beyond the figure.

I have read that some environments such as J2EE application server can achieve some advantage with multiple concurrent VMs, but whether you can use that really depends on your environment.

"Pro Java EE 5 Performance Management and Optimization" by Apress is a must-read for you, if you are managing a JavaEE environment.
