With your settings, I think there will be too much paging happening and the
heap space is the worst place to page.
The reason for the paging is you might have nearly free 2.5GB RAM available
(windows might use the remaining) and you've set the heap space from 3Gb to
6Gb, which will always nearly page.

So, I would say the -Xms1024m -Xmx1500m should be safest for 4Gb, given
that you'd run parallel GC in some memory that will be beyond the heap.
All of this assuming that you have x64 Java as well... just having windows
x64 won't be enough.
