Hey!
Precisely today I recompiled the Ubuntu Breezy kernel with
CONFIG_PREEMPT=y and it made a huge difference! With my M-Audio
Audiophile I'm able to get 2ms latency and lower completely stable!
Before I was only able to go as low as 11ms stable or 5ms with some
xruns... and the performance in general now is way faster! I also
changed to CONFIG_MPENTIUM4=y (as I have a P4 processor) so I'm not sure
if the performance boost is only related to the PREEMPT option (or maybe
both).
cheers!
Hector.
