How much heap does your application need?  Try running with
GC_PRINT_STATS=1 to get an idea of the frequency/duration of collections,
along with heap size.

If the mark phase of collection causes significant paging due to having a
heap larger than available memory, I'd expect some slowdown.  In that case
incremental mode may help.  I have no idea if incremental GC is usable on
win32, though.
