If you're encountering significant swapping with your current heap and
RAM sizes, you might want to consider running with a *smaller* heap
(assuming you can't add RAM, of course).  The impact of paging on
allocation and garbage collection times can be rather significant.  That
doesn't mean you should stop researching your memory usage, of course.
