Thanks for collecting the patches. Very handy.
Quoth Kerin Millar (on Wednesday, the 3rd of August):
Hi folks.
Another interesting point that is not mentioned above is that reducing
the timer frequency can significantly help to reduce time drift
(particularly on "real" SMP systems where this effect may be even more
pronounced). The reason that I am posting is twofold:
What do you mean with "real" SMP?
Is that real as opposed to fake==Hyperthreading, or real as in "more
than a handful of nodes"?

http://www.recruit2recruit.net/kerframil/2.6.12-gentoo-r7-timing-fixes-rollup.patch
strangely enough, the gentoo patch applies cleanly to my 2.6.12.3 tree,
the other does not.
What I would like is for anyone who is interested to put an alternate
value (100 or 250) to the test (if they are in a position to be able
to do so) and to determine whether there is any clear performance
improvement with their workload.
Will report from dual-AthlonXP 1800 system soon.
Cheers,
Peter G.
