Our test files are served from 1000 Mbit/sec links. The files contain randomized data to prevent compression and are large enough to prevent caching and allow the transfer rate to settle. Please note that factors other than your Internet connection may limit throughput, including conditions on your computer or server. If your connection is faster than 50 Mbit/sec, we recommend testing with the 1 GB file.
