Dear Joakim Tjernlund,

In message <OF1413A940.58E7B20E-ONC12576E0.003A9000-C12576E0.003ACFB7@transmode.se> you wrote:

NFS may have some influence here, but I doubt it is the primary cause
for these variations. The network where Heiko is running these tests
is mostly idle, so it should provide fairly constant conditions. Of
coursem the use of the network on the MPC8xx itself will add to the
variation, but again I would not expect so big differences.

Heiko - there is a 10 GB disk attached to the "tqm8xx" system; I
think there should be a usable root file system on it, but I cannot
remember the actual state. Maybe we can use that. Please contact me
on jabber this afternoon!

Best regards,

Wolfgang Denk
