XBMC uses a lot of CPU when I play music. I have a Intel® Celeron® M processor 1.30GHz , 1 cores, a pretty old one I know. But still I hope I can run XBMC on it without overloading.
I suspect the excessive load has something to do with the underlying Login Manager. Here a top output when running with GDM:
I can see the same pattern when running on LightDM.
I tried SLiM, and had very nice CPU usage. But I couldn't here any sound and suspend didn't work either.
Idle CPU load is good, I enabled the dirtyregions setting.
My question:
How can I reduce the CPU load when playing music? Or how can I run SLiM Login Manager and get audio etc. to work?
