I use free web service Speedtest.net to test my speed of Internet Connection, it a good have another web test speed Internet Connection that you know? can share to me.
I use http://www.speakeasy.net/speedtest/ to test my internet connection speed. They give you both upstream and downstream as well as actual data transfer rates.
Same here - been using the speakeasy test for years and love it - I think Cnet also has a speedtest on their site.
I test my internet speed test, through this site IP Details.com : Internet Speed test
It provides the best results for speed test and also has the details about to Search and find ip address’s,domain name host’s who is information including city, country, global latitude & longitude coordinates.
If you use verizon fios then speedtest.verizon.net works. I usually use speakeasy.net but from a fedora linux machine it doesn’t like the flash plugin for firefox and won’t run the test, while the verizon speedtest worked fine.
I suspect verizon’s speedtest won’t run from a non-verizon connection, but I don’t know. Verizon’s test gives you a detailed text results file too, here’s a snip:
