Must be all the christmas festivities that have shut my brain down for today. Anyone got some code, working or suggestions for working out users download speed?

just an idea : you can do it with modify a “preloading script”… u can calculate users download speed per second…  
this means that;get difference between 2 getBytesLoaded(); and calc. download speed per second…

Would be pretty cool, eh? A flash speed-test script in flash… I think it has to be some server-side scripting but I’m sure theres a way to add a tag or something that will make it download differently… It’s beyond me anyways, so phooey

i thought it again, and u can use setInterval(); for calc. DL speed per second…  
maybe this helps u more…

esxs’ first idea looks good to me. You get the amount loaded at one point, you get the amount loaded a little bit after, you substract and divide by the time elapsed. Something like this:

```auto
this.onEnterFrame = function () {
// time elapsed since the last run
var elapsed = getTimer() - this.time;
this.time = getTimer() ;
// bytes loaded since the last run
var downloaded = theClip.getBytesLoaded() - this.loaded;
this.loaded = theClip.getBytesLoaded();
// speed in bytes per millisecond
var speed = downloaded / elapsed;
}[/As]By the way, setInterval would seem very appropriate for this because you can control precisely the timing, but unfortunately, the function is not precise at all...
```
