SpeedTest66 is a fast and convenient tool for testing your internet connection speed. It measures parameters such as download speed (up to 1000 Mbps), upload speed, ping and jitter, and displays them in an interactive realtime manner. The test usually produces results within 5% of the Ookla speed test, and is completed in less than 30 seconds. The concurrent multi-stream implementation allows for a higher precision than just a single-stream approach. The test works on any desktop or mobile device, and because of the pure HTML5 implementation is supported by any modern browser, different from Flash which is unsupported on various devices. Testing for Ping and Jitter values in addition to download and upload speed allows to find out the total quality of your Internet connection, not just the pure bandwidth, and provides a good measurement for whether your internet provider delivers what they promise.
