I just did one benchmark with libvorbis and a large audio file, grabbed
from some random CD here. Results for gcc-2.95, gcc-3.2,
gcc-3.2+march=athlon (in that order):
Elapsed time: 9m 01,0s
Elapsed time: 8m 42,2s
Elapsed time: 7m 26,8s
So change from gcc-2.95 to gcc-3.2 brings only about 4 percent
performance gain, but using CPU optimisations about 15%! I did also try
gcc-2.95 with arch=i686, but it segfaulted while building.
Gruss/Regards,
Eduard.
