said by TOPDAWG:A few weeks ago I had a customer complaining about his speeds because of testmy.net results. This was my response
hm I tried that testmy.net speedtest and it said I was just getting 1.5 mbps and every other test I try says I'm getting my max speed. seems that site is not right.
Another very important factor, where is the server you are testing to located? Looking into testmy.net a little, looks like they are in Dallas, Washington DC (most likely actually Ashburn Virginia) and Seattle. That gives insight into a certain aspect of connection speed--if the only server you ever talk to is in Dallas--but it is not optimal for testing.It does leave me wondering a little though. Is testmy.net credible at all? What good speed test algorithms are easily available? etc. etc.
Of course no speed test is optimal for all uses of the internet. Speedtest.net certainly does give an optimistic result, but I find that is mostly due to multi-threaded download rather than some adjustment factor as identified by the guy who runs testmy.net:
I'm sure something exists that justifies his statement, but.. Speedtest.net gives results that correspond closely with my understanding of how cable internet connections work, so I have good reason to trust the results I get.
Maybe the best way to test your speed is to try a very well seeded torrent. That is still a highly multithreaded download, but it is a real result, rather than a projection based on a brief snapshot.
