a factor of 10 on a binary tree needs some investigation.
i'd be surprised if it's a compiler optimisation (given that it's
recursive, and thus full of function calls, which might i suppose
be tail recursive, but we don't know yet either way).

Could it run faster on other operating systems because of compiler's
optimizations on your program? Maybe 8c makes less optimizations and
code runs slower because of that.
