Martin,
I ran 2.5.54 with an older version of Erich's NUMA scheduler and
with the version sent out for 2.5.53. Results were similar:
Kernbench:
Elapsed User System CPU
sched54 29.112s 283.888s 82.84s 1259.4%
oldsched54 29.436s 286.942s 82.722s 1256.2%
sched54 = linux 2.5.54 with the 2.5.53 version of the NUMA scheduler
oldsched54 = linux 2.5.54 with an earlier version of the NUMA scheduler
The numbers for the new version are actually a touch better, but
close enough to be within a reasonable margin of error.
I'll post numbers against stock 2.5.54 and include schedbench, tomorrow.
Michael
