Based on the test runs that I did using Josh's box (thanks!), the
performance with the pre-allocation patch and an pre-alloc of 8 ends up
being about a wash. Allocating less (4) or more (16) actually makes
things worse. I've been playing with perf to see if I can figure out
what's going on. That hasn't been terribly productive thus far. It's a
bit frustrating. Rest assured, I'll post to the list if I'm able to
make any good headway on improving performance with this approach.
Thanks,
Stephen
