First step is to create a dump file, I just took a ordinary file and renamed it to “data.bin”.

Next step is the speed tester itself. If I figure it out correctly I can take the downloaded time and run it against the downloaded bits to get the speed.

var downloadTime:Number = (getTimer() - timeMarker) / 1000;
var bits:Number = file.bytesTotal * 8;
var bps:Number = bits / downloadTime;

Something like “bps = download size in bits / download secs”

To think of here is that when calculating file size 1mb = 1024kb, but when going for bits whe have 1kbps = 1000bps. Look at this (http://web.forret.com/tools/bandwidth.asp).

How to use
So anyway I created this simple zip file, unzip it on your server, place a file/files in the same folder and then set the paths from the html file, look at line 92, “flashVars”, “files=data.bin”, use , to add more files to load as an array.

This way I could for e.g. check that my connection is 9.6mbit to the net but the speed from my hosting server is 4.5mbit.
