I would try to transfer from /dev/zero to /dev/null via the
network interface.

It might be interesting,
1. if it is a switched network,
2. if there is a lot of concurrency between the network nodes,
and
3. if there are really a lot of PCI cards fighting for the bus
(btw. when I multiply 33e6, 8 and 32, I get 8.4e9... *sniff*)...

There was a similar problem on this list some time ago (maybe that
helps?):
