Hi,
I just noticed a performance regression with rockbox 3.10
CPU usage increased by 15 to 20 percent when playing
Audio playback on maemo 5 is handled by gstreamer / pulseaudio.
Vague guess: The PCM buffer is passed in smaller chunks
The "buffering thread" values in the debug menu
3.9: pcm: x/529200, alloc/real: 7170476
Other ideas what might be wrong?
We should try to figure out if it also affects real hardware targets
Cheers,
