Installation

Assuming you have PHP installed, the installation steps are quite simple. I set this up on a QNAP. For this example, I am using a folder called speedtest in my web share area.

Choose one of the example-xxx.html files as your new index.html in your speedtest folder. I used: example-singleServer-full.html Add: speedtest.js, speedtest_worker.js, and favicon.ico to your speedtest folder. Download all of the backend folder into speedtest/backend. Download all of the results folder into speedtest/results. Be sure your permissions allow execute (755). Visit YOURSITE/speedtest/index.html and voila!
