What I meant is that, if the allocation rate of the program is infinitely
regular and you don't get any threshold effects, the running time decreases
as the minor heap size increases, and it's hard to tell when you should
stop increasing it.

For benchmarks the best choice is probably the physical memory size, but
you certainly don't want your real programs to do that.
