Here are my results from your script.
Tested two kernels, vanilla -test9 and test-9-love2, the latter is a
patchset based off -mm2, including the nick scheduler and
other stuff like reiser4 and bootsplash. More information about this
here: http://bssteph.irtonline.org/linux/patches/2.6/2.6.0-test9/2.6.0-test9-love2/2.6.0-test9-love2_notes.txt
(amd76x_pm-031027 patch backed out, new one put in )
I did three runs each, first run idle, two runs under load, i.e. two
burnK7 processes and a make -j5 kernel compile just to make sure.
loadavg goes up to ~6.5 during those.
ntpd was not running during the tests.
System is an A7M266-d w/ two AthlonXPs 1800+ (model 6 stepping 2),
L5-modded(!) for the MP setup. (I know this is considered tainting,
if you can tell me the timing issues are related to the modding I
will shut up immediately, but so far nobody seems to have pinpointed
it to this.)
The two CPUs show different bogomips (3014, 3063).
