It is known, that ATLAS suffers from the use of gcc>2.95.

But using gcc-3.0.2 or 3.0.3, I can report a reproducible speed gain of
20% in transcode (and maybe mencoder, didn't yet measure this program)
using opendivx output if compiled with the proper -march and -mcpu
setting for my Athlon.

So you can't generalize the speed issues some programs seem to have nor
can you generalize the speed gain other programs seem to have.
