Stream variation

Hi,

This list seems to host a lot of Stream experts, so I hope I won't be too
much off-topic.
Running 2 instances of Stream at the same time on several Netfinity x330
Dual PIII boxes, I see a variation of performance from one node to another
one, from 185 MB/s to 260 MB/s per run for TRIAD for example.

Have you seen so large variation between identical nodes in a cluster
before ? Do you have any ideas ? (temperature, cheesy chipset, ghost in
the machine, ...)

Thanks.
