Another thing worth considering, because it should be easy to do,
is to replace your implementation of malloc and free (the lua
allocator/garbage collector just uses malloc and free "underneath
(well, actually realloc, but hey)).  We replaced malloc and free
in our application and the GC slowed down by about a factor 30, we
then tweaked our allocator and it sped up again.

There are plenty of malloc/free implementations out there ready to use.
