If I shrink the Java heap too much, there's physical

compacts.

There are so many factors, I think the only way to solve this is to do
a binary search to home in on the best value.

See http://mindprod.com/project/tweakable.html

Unfortunately, that best value will change as soon as you process a
bigger data set, or you run something else at the same time.
