Can't edit my comment now, but I did get to wondering... Does speedtest.net include packet headers in its speed? Assuming 40 bytes of a 1500 byte packet is from headers, leaving only 1460 bytes is available for application data, that means that a minimum if 2.7% of my bandwidth is packet headers. So if speedtest.net is only counting application data and not compensating for the bandwidth used by headers, then I should at most see 973 mbps on my gigabit connection.
