====== Speed Test from the Command Line ======
\\ 
\\ 
For a lot of projects, I don't want the GUI, so I have to do everything from the command line (CLI). One thing I do on Windows a fair amount is speed tests, to ensure networking speeds are okay, and now I can do this from the Raspbian CLI.
\\ 
\\ 
Open a terminal and enter:
\\ 
    sudo apt-get install python-pip
    
    sudo easy_install speedtest-cli
\\ 
To start a test:
\\ 
    speedtest-cli
\\ 
You should get an output like:
\\ 
    $ speedtest-cli

===== Some real world tests =====
    On a Pi Zero with a crappy eBay USB Nic I got:
    
    Download: 3.52 Mbit/s
    Upload: 2.91 Mbit/s
\\ 
    On a Pi Zero with a branded (Belkin) USB 2.0 Adapter I got:
    
    Download: 44.40 Mbit/s
    Upload: 17.00 Mbit/s
\\ 
My max DL on my PC is 50Mb/s and my max UL is 18Mb/s, so the Pi Zero and Belkin are working very well.
