There is one thing wrong about these speed tests, people tend to test their connection speed with the nearest speedtest.net server possible, which unsurprisingly yields expected/positive results. For all we know, the person who is doing the test in Uni. Helsinki might not be able to get out of Finland, say to North America - where desired content is hosted - with that kind of speed.
I have an 8mbit adsl connection and without P2P activities I can't even saturate it.
Whether you are downloading a file from google or ms servers, it is highly possible that you would have to settle with annoying speeds even with that kind of a connection.
another test from same origin, apparently it was not just a one time peak.
