Testing Internet Connection Speed with Curl and wget

Hi TEK members and friends try this just copy and paste the following command

curl -o /dev/null http://speedtest.sea01.softlayer.com/downloads/test100.zip

The first thing to point out is that we’re using a test file from Softlayer, but if your connection is really fast, you might want to use a larger file from Thinkbroadband to properly test. Secondly, that -o switch is the lower case form of the letter O. It’s not a zero, and if you omit it, your terminal will turn into crazyville since curl will try to output to the screen — it’s also important because we’re outputting the file to /dev/null, which means it’ll basically be automatically deleted.

Testing Internet Connection Speed with Wget 

If you prefer using wget, or that is what you have installed, the switch is the same. That is a capital letter “o” and it sends the output straight to null, so you don’t have any files to delete.

wget -O /dev/null http://speedtest.sea01.softlayer.com/downloads/test100.zip

This file is only 100 MB, so if you have a really fast connection, this isn’t going to work very well, and you’ll want to find a bigger file to download from the site linked above.
