When I tried it at home a few days ago I didn't get very consistent
results. With gcc 3.2 -O3 -march=pentium-mmx -mcpu=pentium-mmx -mmmx I
got values of about 700, when I reran it, almost 2000 (cache?) and
another time 1300, but steadily decreasing, for my P1-MMX 233.

I haven't tried yet to play with the priority, though.
