We typically run with 4GB, although it now makes sense to use more because of the off-heap and elastic data capabilities. For JVM tuning, the most important thing is garbage collection. We use ConcurrentMark Sweep, incrementally. Through experimentation, we found that NewSize/MaxNewSize=80M and MaxTenuringThreshold=1 keeps GCs at around the 20ms mark.
