When I tested this last year, -O3 on egcs produced a 10-15% slowdown for things like 'gzip'. OTOH, gcc's -O3 produced slightly faster code (as I recall). I /do/ however see noticeable (10-20%) speed improvements using -O2 -mpentium -march=pentium compared to -O2 -mno-486 on gcc. Kris ----- The Feynman problem-solving algorithm: 1.
