I looked at and read netsend/netreceive.  Is this what you are using? 
If so, how do you know that there is no packet loss?  netreceive does no
checking to make sure of anything.  It is just a sink that throws away
the packets.  You need to look at the actual data that is being
delivered.  You will find that 20% of those packets that are suppose to
have been sent are just thrown away without any error indication of any
sort.  netstat -i will show no errors yet the packets are gone if you
look for them on the other side.  So netsend is telling you it sends
them at 38megbytes/sec but out the wire the driver is only sending 80%
of the packets it should.

Cheers,
Sean
