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:

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


Kind regards,
Dirk
