I get about the same numbers on my machine for mp3-playback.

- celeron 800
- sb live! 1024 player
- kernel 2.4.17 (will be 2.4.18 in a few days)
- artsd settings
  o 232ms latency
  o NO full-duplex
  o realtime-priority
  o rest is default I think :)

In general one can say it's all about the drivers today. There seem to be a 
ton of soundcard-drivers artsd cannot cope with or where massive problems 
show up. I have to say I'm rather happy with my SB Live! and I won't buy a 
different soundcard in the near future :)
