Why does XMMS2 use so much CPU - nesciens/xmms2-wiki GitHub Wiki

"xmms2d uses N% cpu, whereas $otherplayer just uses M%"

This page should be fleshed out to a real guide on how to debug these things.

insert info here about how to

• output plugin issues?
  • Does it happen with "null" output plugin?
  • Only happens with alsa? Try setting bare hw as device ("xmms2 config alsa.device hw:0" or similar)
    • If using dmix, check if resampling is taking place. More info and troubleshooting.
• look at chain (effects, converter).
• compilation with -O2/-Os (+ add reasoning why it isn't default)
• make sure medialib indexer isn't running
• compare with madplay / mpg123 (+ reasoning with int/float)
