Re: 2.6.21 -> 2.6.22 & 2.6.23-rc8 performance regression

[Denys]

Hi

No major differences. 
Some procedures higher a bit, some lower a bit, but everything looks fine on
both kernels.

Thats what i tried first - oprofile, and only one keypoint i was able to catch
- in top softirqd/0 or /1 shows usage 100% cpu, and in mpstat - soft% also
reaching 100%.
