Sorry, I wasn't clear.  It sounds like you've got two very different
copy speeds on two possibly different data sets.  The problem will be
significantly easier to debug and discuss if you boot a 2.4.19 + data
logging kernel, do the test, and then do the test again on a 2.4.21-pre
data logging kernel.

I know this is a pain, I want to reduce the number of variables in
place.

Oleg is making patches for the -ac series.  He also merged a special set
for Philippe, they pay namesys for support ;-)

I'm remerging my work over the last week and should have a new set of
patches out soon.
