Speedtest.net allows you to measure and compare the performance of your broadband connection.
Analyse and test the true speed and performance of your broadband connection.
With an interface resembling the dashboard of a sports car, you can test the bandwidth speeds between you and a vast selection of geographically dispersed testing servers.
Following the test you are shown the download bandwidth speed (speed of data from server to your computer) and the upload bandwidth speed (speed of sending data from your computer to the server).
It is possible to view your past results and compare your result history with other broadband users in your area. There is also a tool that allows you to get stats on their entire database of test results. These global stats can be filtered by country all the way down to city level.
Everything is done via your web browser, so there is no need to download or install anything.
