That sounds really small to me. The literature I've read on generational
GCs with a "nursery" [e.g., Ungar, Appel, or especially Wilson et al
<http://www.cs.utexas.edu/users/oops/papers.html#caching-gen-gc>] making
the nursery [your young heap] be roughly the size of the CPU's secondary
cache [but not larger].

Also, be sure you keep the nursery in a fixed location [if you're not
already doing that], since the whole point of that approach is to keep
the memory in the nursery "hot" in the cache.
