I would start below the cache size. If that works that is really great.

Limit it by the size of the major heap (at most 10% of the major heap
size?). And grow/shrink it by amount of copying to the major heap that
is required. If less than 10% of the minor heap are still alive on a
sweep then shrink it, if more than 50% are alive then grow it or
something.

Do a lot of tests to find good values for those percentages.
