Ok, then it's something else, maybe the TSO changes...

Here's some thigs to try:

You can see the current settings, TSO etc, with

'ethtool -k eth0'
and disable TSO with
'ethtool -K eth0 tso off'

If that doesn't help there's more things to try.

I don't know anything about the diffrent TCP congestion algorithms
(Stephen does), but you could try disabling BIC.

echo 0 > /proc/sys/net/ipv4/tcp_bic

(continuing with things I hardly know anything about...)

Or maybe the autotuning receive buffer, try disabling that with

echo 0 > /proc/sys/net/ipv4/tcp_moderate_rcvbuf


Stephen, any more things to try ?
