That is awesome, thank you Simon. With sendto, empty packet sending rose to 81.99Mbps which is much better. It occurred to me that we actually only have one destination and once set it rarely changes so I switched back to netconn_send/connect but moved the connect outside the main send loop, performance was 82.13 Mbps, re-instating the packet copy used in the standalone benchmark dropped this to 75.3Mbps.
I am going to try the tcpip_callback() next. Any chance you could send those files to me directly, my company's web policy is stopping me downloading the tar.gz file from the git repo and TortoiseGIT, so I can't actually get them :( I assume that they are ok to use with 1.4.0?
