[DONE]Javascript Speed Tester.
This is a little something I created in a day. It's just a little something I wanted to see if it worked or not.
Average Speed Tester(AST) Here
Tell me what your comments are on it. Do you think it's accurate?

Update:
- Now an average speed tester. Test your average download rate through using multible downloads.
- Displays average KBps, Bps, kbps and bps.
- New progress bar with clean and suiting look.
- Supports Firefox and IE not Opera 9 (weird image resizing, post if you know how to help with this issue)

Ok, I'll bite...It's neat...I assume it's testing...bandwidth speed?
I'm sure it's accurate...but how accurate I don't know...there are more than a single variable that must be considered when calculating bandwidth...
For instance, your physical geographic location has an impact on how fast you download files from site A as compared to site B. The further you are from the source, the more hops your data likely has to make inorder to get to you, but this isn't always the case. Then, if your downloading files from a computer somewhere and it's connected at 56K dialup...obviously no matter how fast your connection is, you'll only be capable of downloading at the speed at which that computer your connected too will allow you...
Those bandwidth test sites likely are connected to the Net using major backbones to gaurantee they will allow download faster than a normal household connection...
These are two major factors I would think those bandwidth testing sites take into consideration and and act on that appropriately to give slightly more accurate results...
Whats the two number for...one is average and the other is max???
I got 20 over 160 and I tested 5-6 times...???
300 is the fastest I download...but the 2-300 mark is usually only ever from sites like Intel or Microsoft, etc...big corps...20-40 is what I get from most other sites
Cheers

I don't know what you mean? The results display the average speed at which you downloaded ten seperate images in:Whats the two number for...one is average and the other is max???
- kilobytes (KBps)
- bytes (Bps)
- kilobits (kbps)
- and bits (bps)

Code? 
I guess you just generate a timestamp on the server right at the start of the request, then onload you calculate the difference. You'd really need to take into account the time the server took to process its response but that's not going to be particularly easy to do. Can't really give much feedback without seeing all the code which makes it up (not just the JS).
EDIT | Ah ok I see, it downloads images. How do you account for what time the server takes to deal with the request?

Thanks d1wtq, it's just a little app I wanted to try for practice. And just wanted to see if images can be used as to test ones speed, don't know if it's been done before but now I know it has.
It seems to be pretty accurate just some display errors with opera and I don't know all the functioning it can do with diferant OSes but I did support win 98 and xp, pretty sure.
Anyways that's that. Cheers.
