Speedtest is crap. Seriously. They consistently overrate my connection speed by 15Mbps.

As near as I can tell, many ISPs (I have Cox Cable internet) use modems that do compression. Speedtest.net appears to use test-data that is highly repetitive.

The end result is they often overestimate your connection's speed by as much as 100%!

DSLreports and TestMy.net both use largely incompressible data, and seem far more accurate. I still get a fair bit of variance between their results (and variance between the different types of test), but they're in a far more believable regime than speedtest.net.

    Speedtest works for me but you raise a good point (+1). The correct answer should probably be to try two or more sites to test your speed. – Nifle Aug 11 '10 at 11:36
  • Since this question is a duplicate, I suggest you add your answer to the original one, to keep all possibilities on the same place. – Gnoupi Aug 11 '10 at 15:32

http://www.speedtest.net does the job nicely.

  • As I commented on a similar posting, Speedtest is not reliable. One time, I had superceded a cap on my data on my connection, so the ISP had cut the speed down to 128k. Speedtest.net consistently told me I had 18m! And when the ISP reinstated my normal speed, Speedtest.net's result didn't change. Either the ISP is gaming the results, or simply Speedtest.net is not accurate. – TrojanName Sep 18 '12 at 10:24
