Interesting. For the most part, I've been impressed that my cheapo
Celeron-333 performs pretty close to a PII, but I'm not finding that
with your last version of the code...
Original: about 40
With floats & integer phase accum.: about 110
compiled with egcs -O3 -funroll-all-loops -m486 -ffast-math
Any idea why it's so far behind? (110 vs. 565 at same mhz!)
I know the cache memory is much smaller. Could that account for it?
