DOCSIS has some support for stream compression, so you'll often get highly unrealistic results.
On the other hand, basically all internet content is sent over the wire already compressed, so any stream compression doesn't help with it at all.
I've had speedtest.net overrate my connection by 2-3 times it's actual throughput.
