I get 700~800 Mbps myself but that might come down to the setup. You could say it affects performance slightly, as I saw in a previous email. Without the setting The rate consistently drops to 0. ethtool reports tx-checksumming is on in both cases Pretty cool! Does that give you guys an idea on how to tackle it "officially"?
