These tests measure how long it takes to load a test page from its server, and display it on your browser.
Modem configuration, ISP bandwidth, Internet congestion, and many other factors can affect the 'download time'.
That said, the test should still be a good indication of how fast or slow your data transfer rate over the Internet really is.
Because the tests avoid reloading from your disk cache, you can repeat the tests as often as you like.
The modem speed test pages are designed for, and tested on, ordinary analogue dial-up modems, and ISDN modems.
Results of tests for other 'high speed' modems, such as, cable modems and xDSL modems, may be in-accurate.
