One thing I noticed a while ago (march) is that floodpinging (ping -f)
the r8169 host from an external system also increases performance
without changing code.

My original post about the problem:
http://marc.info/?l=linux-netdev&m=117207362010321&w=2

I ended up (until now perhaps :-) with disabling the onboard nic and
adding an e1000 card.
