It would be good to test, though I know that at least dummynet is written awful from the point of this project with its callout_reset(&dn_timeout, 1, dummynet, NULL); It should work, but kill most of power benefits. I was promised it will be fixed after this project end. > What else gets heavily callout /timer driven? Try some computational > workloads that stress the fairness of ULE/4BSD, maybe? Schedulers are driven directly by hardclock()/statclock(), so fairness is not affected here. If CPU is not idle, it will receive full set of required events with maximum available precision. -- Alexander MotinReceived on Mon Dec 17 2012 - 07:14:34 UTC
