That's great, but what impact does it have on access to individual
elements? If you're not careful, you may find that accessing stuff in
the array gets quite seriously slower. Linked lists being O(n) access
and all that...
What other differences are there between grey and CVS? For me, this
says that the CVS's main despatch loop, the PMC infrastructure and
most of the GC is pretty tight and most of the slowdowns are in the
actual PMCs themselves.
So, two suggestions:
Put another loop in, which sets I1 to every array element in turn,
(maybe make this an inner loop which runs each time you extend) and
re-benchmark.
Throw gprof at both of the builds and look at the differences.
