I would point the finger at the Linux implementation of the mpg123
routine, which is a heavier load on Linux than on other platforms it is
implemented from my past experience, and is heavier than various other
mp3 utilities from my experience. I used mpg123 on both Linux and OS/2
on my old Pentium 90 MHz box with its 80 MiB of RAM, and it was smooth
under OS/2, but to keep it from breaking up under Linux, I had to cut
the sampling by 4 and settle for mono playback. MPG321, meanwhile, has
always been fine.
