Basically, you test it. Check out SpeedTest.net for an example.

You download a file, and then upload it and measure the times.

Most of the online speed testers use flash for this purpose, so the user doesn't have to worry about browsing for a file to upload.

Thanks, but am talking about doing it in php and vb.net – Smith Dec 31 '10 at 03:38
@Smith, Yes, and the method doesn't change. In a VB.NET WinForms, download a file from your web server and measure the time it takes. Then, POST it back and see how long it takes. http://stackoverflow.com/questions/92522/http-get-in-vb-net http://stackoverflow.com/questions/981354/how-to-post-a-file-via-http-post-in-vb-net PHP comes into play when posting the file back, as something has to receive that data. – Brad Dec 31 '10 at 04:26
that would give me a static speed , where in real world, it varies by the second. sometimes up, sometimes down. how do i show this variation live? – Smith Dec 31 '10 at 08:10
@Smith, you check it over and over again, or continuously download and check the speed over the last second, or some interval. Of course, by doing this you are sucking up a lot of user bandwidth, and I don't imagine this is what you're after. What are you trying to do? – Brad Dec 31 '10 at 17:25
