Have you tried running it without an altered priority level (altered by you
that is)? I run freeamp without any special nice level and running it while
dbench is pushing the system into 25 load or something else is throttling the
system at 100% cpu and hogging 200MB of ram - it never skips. With or
without the patch. Some programs actually suffer from changing from default
priority. i see that with hdparm -t sometimes. This is on a 850Mhz athlon,
by the way. I find mpg123 to be slower than most other players. Try some of
them. If you're console only, freeamp is both a console and gui mp3 player.
I imagine xmms would be pretty fast too when you turn off any extras.
