No Flash, No Java, No Websocket, No Bullshit.

This is a very small (4k) Speedtest implemented in Javascript, that relies only on XMLHttpRequest.
|
||||
This is a very small (4k) Speedtest implemented in Javascript, using XMLHttpRequest and Web Workers.
|
||||
|
||||
## Try it
|
||||
[Take a Speedtest](http://speedtest.adolfintel.com)
|
||||
|
||||
## Compatibility
|
||||
Microsoft Edge, Firefox 10+, Chrome 10+, Opera 15+, Safari 7 (not tested)
|
||||
Only modern browsers are supported (Edge 12+)
|
||||
|
||||
## Requirements
|
||||
- A reasonably fast web serve
|
||||
- A reasonably fast web server
|
||||
- Some way to generate garbage data using either the included PHP script, a [big file of random data](http://downloads.adolfintel.com/geth.php?r=speedtest-bigfile), or a symlink to /dev/urandom
|
||||
- Your server must not compress the data it sends
|
||||
- Your server must accept large POST requests (up to 10 Megabytes), otherwise the upload test will fail
|
||||
- Client side, there must not be any type of buffering (such as a proxy), or you may get incorrect results
|
||||
|
||||
## How to use
|
||||
See example.html, it's not rocket science.
|
||||
See the examples, it's really simple.
