# Speedtest in 4k
# HTML5 Speedtest
No Flash, No Java, No Websocket, No Bullshit.
This is a very small Speedtest implemented in Javascript, using XMLHttpRequest and Web Workers.
This is a very lightweight Speedtest implemented in Javascript, using XMLHttpRequest and Web Workers.
## Try it
[Take a Speedtest](http://speedtest.adolfintel.com)
@ -13,9 +13,9 @@ Only modern browsers are supported (Edge 12+)
## Requirements
- 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
- It's also better if your server does not use compression, but it's not mandatory
## How to use
See the examples, it's really simple.
