I haven't run many tests on it - my mind blanked when I tried to

anyone would like to suggest some, or better still, run some,
please do so. And be nice, this isn't my type of scheduler :P



I timed a pathological benchmark from hell I've been playing with lately.
Three consecutive runs following a fresh boot. Time is in seconds:

2.4.21 821 21 25
2.6.0-test3-mm1 724 946 896
2.6.0-test3-mm1-nick 905 987 997

Runtime with ideal scheduling: < 2 seconds (we're thrashing).



Cool. Can you post the benchmark source please?
