so many questions :-)!

the test were run many times, on host C the port was changed, the cable was 
changed, the NIC was changed.

the disk is not relevant, the test uses a small program i wrote that writes
from memory.

at the moment all three run the same version of the kernel, the only diff is
that A & B are smp, and C is not.
