Wow, gcc 3.1.1 generates some superior code indeed. I've included my new
results. The encoding rate results WRT -q setting haven't really changed
that much. The interesting thing was that gcc 3.1.1 gave me way better
than 10% increase in speed in some places.
All tests are conducted with a wav file being read from a RAID0 array of
two disks and written to a third disk as ogg to reduce disk IO
bottlenecks (I doubt there would be anyway, but hey...). The disks may
or may not share a controller. I don't care enough to check...

I have a switch in my apartment... it doesn't do anything.... Every
once in a while, I turn it on and off.... One day I got a call...
it was from a woman in France.... She said "Cut it out"....
