Well, I'm writing a sequencer. I was trying to figure a way to achive low callback
latency to update
my mixer, without using any "extra" (such as /dev/rtc). My approach was quite simple,
I just spawned
a high amount of threads, each with a sleep(1) and updating the player timer all the
time.
Surprisingly, this works amazingly well, and the more the threads the better the
performance, now under heavy load (and without patching against low latency) the
player latency is allways around 10ms (the minimum you can get from the x86 clock). I
hope this information is of any use!
