Hello all

Im hoping someone can help me in here on my quest to find a download speed estimator script. I have been looking all over the place and keep coming across a few javascript ones. Although these are good im looking to have a drop down box where they select their connection speed and then it gives a simple time result (estimated) I do apologise if this is posted in the wrong place as im not surw wether it will be javascript or php?

Edit: Come to think of it, is it possible for a script to auto detect their connection speed and auto display approx times?

Any help and suggestions appreciated.
Thanks
Nick

That is a very interesting question!

You need to find a way to measure the time it takes for the user to download a given file (its important that you measure the download, not the upload speed of the user, else you misjudge DSL connections completely).

But frankly, I don't know yet how I would do that!

One way that this could be done is:
1) the server logs what time the speed test is requested

2) you would then have a default file with a set size to download i.e 1024K

3) once the file has finished downloading the page would then call back the page and find the difference in time using the server. From this you will need do some simple maths and find the average KB/sec i.e. if 1024K took 10 seconds to download then you would know that the connection was running at 102.4KB/sec(also if I remember correctly on average 13% is in overheads if you want to get really accurate). The bigger the file the more likely that you get a more accurate number as the connection would stabalised.
