TestMy is the most unrestricted bandwidth speed testing resource on the Internet. Most don't even tell the user how much information has been transferred, takes a different approach. No other major broadband speed test offers testing with such large files. TestMy has a unique testing method and can help you diagnose connection, browser and operating system issues that other speed tests fail to detect. People keep choosing because the results have been proven accurate and reliable. This bandwidth speed test has been in development since 1996 and has benchmarked performance on millions of Internet connections. TestMy's proprietary method is proven to help identify issues other speed tests fail to detect.

This isn't like any other broadband speed test. This speed test is useful if you feel a connection slow down or want to see how your Internet is performing. Simple, to make sure you're getting what you pay for. has been pioneering the bandwidth speed test since 1996. First to offer the ability to log test results, test upload speed and automatically test Internet speed. We work for the Internet consumers not the Internet providers. Our results are unbiased because TMN has no vested interest in the outcome of your speed test. is an independent third party and is not affiliated with your Internet service provider. Increased latency decreases the TCP window is a powerful broadband speed test that will test your Internet, calculate your transfer rate and output accurate, reliable and easy to understand results. The larger the window size, the higher the speeds. The TCP window size determines how many packets can be sent at one time. This is because the TCP window is not optimized for the increased latency that comes from an increase in distance. You have likely noticed that downloading from a local server location is also faster than a distant one.

Our speed test server is modelled to reflect normal browsing across currently available websites. Also, the third party site may not be using test files that are large enough to permit an accurate reading for speed tiers with higher speeds. This counteracts the ability to reach higher speeds, as there is more wait time from the packets being sent and received from the third party speed test server.

In addition, the third party's test engines could be using a single threaded TCP connection during testing. Those 'peering' networks may have an effect on the overall speeds. For example, when using a third party speed test site, your traffic may travel over networks that are not controlled by Gibtelecom. There are a number of other variables which could impact your speed test results from a third party test site. The results from Gibtelecom speed tests represent an estimate of the maximum connection speeds for downloading and uploading with a test server hosted within Gibraltar.
