2019 Update
==========
I don't have a lot of time to work on this code anymore. I may post updates from time to time, but at the moment this software is mostly abandonded. I am working on a Rust implementation and will post more details here in the future. See https://github.com/zpeters/speedtestr

Thank you for all of the fun and support over the years.

VERSION 2.0 Testing
===================
Initial testing release of v2.0 is out for the testing. See "releases" for downloads. The current "test" is hard coded and there are no options at the moment. Please send me any feedback at [email protected] or through the issues.

The Unofficial Speedtest CLI
============================
The Unofficial Speedtest CLI is a command-line program to test
bandwidth in situations where you don't have access to a full GUI
environment and web browser.

In [2013 I was feeling guilty](http://thehelpfulhacker.net/2013/07/29/giving-something-back/)
about using Open Source software for most of my life without giving
anything back in return. I decided to create this project to my part
to help the IT community.

A lot of the initial algorithms here are based on different scripts I
found when I was studying how speedtest.net works. Mainly, @sivel's
[speedtest-cli](https://github.com/sivel/speedtest-cli),
thanks for your work!

Why don't my speeds match those reported from the speedtest.net website?
========================================================================
The calculation that is used for testing download speeds is literally measuring the amount of data we are downloading (we request a "random" image and count how many bytes are received) and how long it takes to download. We multiply by the correct factors to get from bytes to megabits. I consider this to be an honest and accurate measurement.

In speedtest.net's reference documentation they describe doing a lot of manipulation to the results to return an "ideal" measurement (https://support.speedtest.net/entries/20862782-How-does-the-test-itself-work-How-is-the-result-calculated-). This, to me, is trading accuracy for speed and not what I'm looking for out of a testing tool.

For confirmation that my download calculations are correct I have tested against a few other speed testing sites, specifically http://testmy.net ("What makes TestMy.net better") who appear to use an "unfiltered" method of calculating bandwidth speeds. These results typically match up with speedtest.net cli
