thanks for testing this!


wow - really nice graphs!


wrt. yield4 did you set /proc/sys/kernel/sched_compat_yield to 1? 
(with sched_compat_yield at 0, which is the default, nothing 
changes)

which one would be your favorite kernel? To me yield4 looks pretty good.


i'm wondering, how easy would it be for you to test the sched-devel.git 
tree? If you havent used git before then first install the 'git' 
package, then do:

  git-clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git linux-2.6.git
  cd linux-2.6.git
  git-pull git://git.kernel.org/pub/scm/linux/kernel/git/mingo/linux-2.6-sched-devel.git


ok.
