This looks like something for the sched people. Adding Mike.
So, a couple of observations I was able to make; I want to highly
emphasize here that I'm no sched guy.
* AFAICT, your synthetic benchmark sets sleep intervals of about 1 ms
which is very close to the scheduling latency I was able to observe
through watching vmstat while building the kernel. It showed 800-900
context switches per second which is something a little more than
1ms. I'm not sure the stock kernel can even handle such small sleep
intervals.
* You're saying, you're observing degraded music playback and gaming
quality. How can I reproduce that?
* Then, have you considered running the realtime kernel? A lot of people
prefer it because it solves a lot of latency issues related to audio,
a.o.
Thanks.
