If I have a high-end server, for example with 1T memory and 8x4core CPU...

will it bring more performance if I run multiple App Server (on different JVM) rather than just one App Server?

On App Server I will run some services (EAR whith message driven beans) which exchange message with each other.

btw, has java 64bit now no memory limitation any more? http://java.sun.com/products/hotspot/whitepaper.html#64
