No I can't reproduce the performance degradation.
I think that it was a wrong interpretation from myself

I apologize for this wrong information


I have rerun the same code, compiled with gcc (4.1.x), and I can't get higher numbers with gcc than icc.

and with gcc, I'm not so far from the eth2 limit (~1GB/s)

> dstat -n -N eth0,eth2
--net/eth0- --net/eth2-
 recv  send: recv  send
   0     0 :   0     0
