bwtestjs

This is a jquery-based speedtest tool which is inspired by JQSpeedTest: https://github.com/skycube/jqspeedtest

It is slightly different in the following ways:

1. It does not generate a random string for upload, it uses the same files that were used for download to perform the upload
2. JQSpeedTest had the problem that for fast connections, a single TCP connection could often not overwhelm the connection. This tool allows for multiple parallel TCP connections inspired by iperf3 -P <# of parallel requests>.
3. This test has different connection speeds in mind and can scale up the test so that it starts with slow connections and gets more and more demanding if the connection can handle it. For instance, it starts with a 20kb file which should be downloadable on a 28.8 kbit/s connection in 5 seconds. If this happens fast enough, it will proceed to a 40kb file which should be downloadable in 5 seconds on a 56.6 kbit/s connection. This continues all the way up to a 1Gpbs connection with the target time of about 10 seconds for the total test.

Instructions

1. Clone the repo into your webserver
2. On the webserver, run the generate_data.sh file to generate the data files.
3. If you wish to have a separate server to handle the load of the bandwidth tests, host the test transfer files on that server, and set the server url in the configuration.
4. On the client webpage, use jquery's onload, or attach a button click event to starting the bandwidth test.
5. Tie-in to the event-driven callback functions to handle the results of the test.
6. (optional) Open the developer console in chrome / firefox to see logging and network traffic during the test
