If you want to check the current internet speed of your Linux server from the command-line, you can use a utility called fast – a minimal zero-dependency script, written in Go language for testing your internet download speed from the terminal, which is powered by Fast.com – Netflix and runs on Linux, Windows and Mac.


This speed testing tool is very simple and has no options whatsoever. Simply, download binary file for your architecture (fast_linux_amd64 for 64bit systems) in your home directory, set execute permission and run it directly from the terminal to test your server Internet speed.

$ wget https://github.com/ddo/fast/releases/download/v0.0.4/fast_linux_amd64 -O fast
$ chmod +x fast
$ ./fast


If you want, you can install it under /usr/local/bin directory on any Linux distribution by using the following commands.

$ wget https://github.com/ddo/fast/releases/download/v0.0.4/fast_linux_amd64 
$ sudo install fast_linux_amd64 /usr/local/bin/fast
$ fast


You can also install Fast on any Linux distribution using snap (requires snapd to be installed on the system).

$ snap install fast
