Could this BIG difference be just because 2.6.37 was compiled with CONFIG_HZ=1000 and 2.6.34 with CONFIG_HZ=250 ? That much impact?
The -default flavor always had CONFIG_HZ=250, and the -desktop flavor had CONFIG_HZ=1000. So check if you are not comparing different flavors by accident.

Thank you for pointing this out. I was really comparing different flavor configs, but I am *almost* 100% sure I compared both default flavor on my .34 vs. .37 tests. I am rerunning things now again ....
I can confirm that I still see the 80% slowdown, compared again on the same flavor kernel, both desktop ones running with CONFIG_HZ=250 . My first mail from today stating that CONFIG_HZ were different was just my error, comparing different flavor configs. The tests were ran (and reran today) with the same desktop flavor. Any ideas? Anyone? Michal? Thanks, Richard -- Richard Ems mail: Richard.Ems@Cape-Horn-Eng.com Cape Horn Engineering S.L. C/ Dr. J.J.
