Your application is a loop that decodes vorbis as fast as possible,
then when it gets to the end, it restarts.
If you speed it up, it'll STILL run forever, and use 100% cpu while
it's doing that.
Is there a particular problem you're trying to solve in a real
application? If you explain that, we might be able to help (as a
reference point: decoding 44.1kHz stereo vorbis takes less than 1% cpu
for me, on average).
