Dual Xeon 2.4GHz, a 82540EM and a 82541GI both on 32/66 on separate
PCI buses.
BEFORE performance is approx the same for both, ~620kpps.
AFTER performance is ~730kpps, also approx the same for both.
(Note: only sending with one NIC at a time.)
Once or twice it went into a state where it started spitting out these
kinds of messages and never recovered:
Dec 1 19:13:18 phi kernel: NETDEV WATCHDOG: eth1: transmit timed out
[...]
Dec 1 19:13:31 phi kernel: NETDEV WATCHDOG: eth1: transmit timed out
[...]
Dec 1 19:13:43 phi kernel: NETDEV WATCHDOG: eth1: transmit timed out
But overall, looks good. Strange thing that Robert's numbers didn't
improve. Doing some more measurements right now.
