+# Speedtest in 4k
 
+
 
+No Flash, No Java, No Websocket, No Bullshit.
 
+
 
+This is a very small (4k) Speedtest implemented in Javascript, that relies only on XMLHttpRequest.
 
+
 
+## Try it
 
+[Take a Speedtest](http://speedtest.adolfintel.com)
 
+
 
+## Compatibility
 
+Microsoft Edge, Firefox 10+, Chrome 10+, Opera 15+, Safari 7 (not tested)
 
+
 
+## Requirements
 
+ - A reasonably fast web serve
 
+ - 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.
