Thomas, I played with the chess2.pov benchmark a couple years ago on the
same 375mhz processor. With simple optimizations I saw about the
performance you saw. I was able to get it down to about 21 minutes using a
bunch of optimizations, but never really understood why the performance was
so much slower than comparable powerPC processors in Macs...
