Actually, a minimum of 900Mbps is reasonable to expect from a good chunk of speedtest.net servers. The test being run here is to GOOGLE'S PRIVATE test servers, which is why I wanted to see some public test server results.
Proof that quite a few speedtest.net servers can handle 1Gbit+: »i.imgur.com/Qx9MH.png
I don't deny that testing the upload is difficult, and I don't expect to see gigabit upload at all. However, 900Mbps+ download speeds is a reasonable expectation. I've seen quite a few other people with servers that see similar results with their gigabit/multi-gigabit lines.
