speedtest-cli

This is a simple terminal script that uses the speedtest.net API. This is based on Python, so it should work on any operating system supporting Python v2.4 and above. It is developed by Matt Martz and can be found at his GitHub repository at https://github.com/sivel/speedtest-cli 

The scripts were adapted to work with AmigaOS 4. To use it, just double-click its icon and a new shell window will open. Automatically, a close server will be chosen, and it will measure the download and upload speed of your system.

More parameters are available for the script, and you can find them in the included document README.rst.
