I think I found the problem. It seems that there is some component in
the network path (probably a switch) that does not queue all the packets
of a burst of the outgoing GB adapter. If I rate limit the server GB
interface to 80mbps, I get something like 60mbps for tcp transfers.

Thanks a lot to everybody.

Cheers,
Andres
