I also have some 7.2 boxes with great performance. Using iperf I did some tests: server(8.0) <- client (8.0) == 420Mbps server(7.2) <- client (7.2) == 950Mbps server(7.2) <- client (8.0) == 920Mbps server(8.0) <- client (7.2) == 420Mbps so when the server is 7.2, I have good performance regardless of whether the client is 8.0 or 7.2. when the server is 8.0, I have poor performance regardless of whether the client is 8.0 or 7.2. Has anyone else noticed this? Am I missing something simple? TIA Elliot
