TCP Checksum Offloading, important in NAT since it has to re-checksum each packet that it rewrites. This was just running speedtest.net, can't say I bothered to measure the packet rate because a normal HTTP download had the same effect. I ended up running into more issues when I switched from ESXi to XenServer so I don't really have the ability to recreate the results, I would probably have fewer issues if it was running on bare metal (and I'll probably switch to that eventually).
