I've tested it on my XP machine and it was able to detect my Internet speed in the UK, Ireland, and Canada.
Speedtest verifies the connection speed between a testing server and your system, utilizing your computer's internet connection. Several aspects can affect the actual speed measured by a testing server: Different computers (ostable devices, PCs, laptops, etc.) and wireless routers
Speedtest verifies that the connection you are experiencing isn't just the typical dial up or DSL service, but is a quality "real" broadband connection which supports streaming video, real time web recording, and various other features you'd expect from a modern PC. It can be used on any operating system, including Windows 2021, Windows NT, or Windows Vista. Speedtest verifies that the connection you are experiencing has the highest available download speed, with minimum delay. Speedtest compresses the speed difference it measures, so it's very fast.
