optimal memory settings for following setup

Unfortunately it's tough to give advice since while I understand your tests are modularized, that still wouldn't tell us how heavy it is on memory.

I personally set xms pretty low since then the program won't take much memory on startup. But I increase xmx value to avoind "OutOfMemory" errors. But again, these preferences would differ per application and need.
