Firstly, let me say that if your application is multi-threaded, then it is already taking advantage of multiple cores. In Java, threads will use all the available cores by default. So, if you are using GridGain to grid-enable your application, your application will take advantage of multiple cores just because GridGain is multi-threaded on its own.

Hi,
What you say might be true for 32 bit machines. In practice on 64 bit machines (at least with the SUN JVM and the concurrent mark and sweep collector turned on) a bigger heap usually gives better performance.
