Ha, you might be interested in the latest thing we are working on upstream. We discussed it last week at Linux Plumbers. We are calling it latency-nice (but as all good programmers know, naming is hard and this will probably change). Right now the scheduler is not too good at figuring out which process should get a place to run at quickly, and by providing a latency-nice tunable, you can ensure your latency sensitive processes are placed on the runqueue quickly. Keep an eye out for this, hopefully we will get it upstream in a few months. Dhaval > --dave > > -- > David Collier-Brown, | Always do right.
