Ok, I've done a crude comparison of a bunch of the jobs we run between
2.6.22 and 2.6.22-git1 kernbench runs, extracting the wallclock, user
and system times for each. First column is 2.6.22, second is
2.6.22-git1, third is the delta. +ve bad, -ve good. Note that I have
hand correlated these jobs so error is possible, but it matches Martin's
figures I belive.
