This is to keep the statistic more accurate. - Charge a parent one tick for forking a child. - Add only the run time and not the sleep time to the parents kg when a thread exits. This allows us to give a penalty for having an expensive thread exit but does not give a bonus for having an interactive thread exit. - Change the SLP_RUN_THROTTLE to limit us to 4/5th and not 1/2. - Change the SLP_RUN_MAX to two seconds. This keeps bursty interactive applications like mozilla and openoffice in the interactive range even through expensive tasks. - Recalculate the slice after every sleep. This ensures that once a task has been marked interactive it only has a slice of 1 at the risk of giving tasks that sleep for a very brief period a longer time slice. |
