It's time to report the data again to keep everyone informed. Here is the latest result that we measured (4P 1.6GHz ia64, 9M L3 cache, 64GB memory, 480 15K-RPM disks). 2.4.21-4.EL baseline 2.6.9 - 6.00% 2.6.11 -13.00% 2.6.12-rc3 -13.54% 2.6.12-rc4 -13.05% 2.6.12-rc5 -12.86% 2.6.12-rc6 -12.66% It's been hovering around -13%. I will take a measurement of 2.6.12, though I don't expect it to deviate too far from 2.6.12-rc6. There are 718 patches committed since 2.6.12 as of 6/22 14:09 PDT, so I'm going to take a snapshot today or tomorrow and queue it up for benchmark measurement. I will probably take all the scheduler patches currently in -mm and give that a whirl as well. - Ken
