Did you have jumbograms enabled? If you disable them, but leave the mtu at

Euh... I bet he meant with big MTUs. Turning jumbograms off on a
standard Ethernet MTU actually degrades performance, just tested:
107 MB/s -> 94 MB/s (admittedly a quick, non-scientific test, on
Andrei Maslennikov's hardware, GigE, MTU 1500).
