I think that if the problem of a single scheduler which is "best" at everything proves out of reach, perhaps in 2.7 a modular scheduler will appear, which will allow the user to select the Nick+Con+Ingo responsiveness, or the default pretty good at everything, or the 4kbit affinity mask NUMA on steroids solution. I have faith that Linux will solve this one one way or the other, probably both. -- bill davidsen CTO, TMR Associates, Inc Doing interesting things with little computers since 1979.
