Yes, that's what I expected. It's good to see the match as it validates that
what we're measuring in tinyBenchmarks is in fact a realistic measure of
average bytecode performance. I wasn't entirely sure about this given the
wide spread I obtained in my own measures.

Now that's interesting to see! It all looks as if the PPC is really *much*
less affected by branch prediction issues. BTW, the numbers you sent around
in the first message only said "using mac vm 3.5.2b1 (500Mhz G3) - were
these taken from a gnuified VM? If not, could you run the two benchmarks to
see if they have any effect?

Thanks,
