Bug#521727: Preempt
I can confirm that.
While the difference between PREEMPT and normal kernels with 2.6.18 and
prior to that was mostly "for connoisseurs", with 2.6.26 it is clearly
visible with the naked eye (tested on a bog standard 2GHz Athlon XP).
This should not really be the case especially under light or no load.
There is yet another performance regression somewhere besides the NFS
one and the block IO one which got fixed recently.
