I looked at and read netsend/netreceive. Is this what you are using?=20 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.
