AJAX Counter and Update Panel help needed !

I am making a clone of quibids.com in asp.net. This site is in PHP. Can anyone check it and tell me which technology / language they are using behind those so many running counters at the same time ? Is that server side counter or client side counter ? I have tried ajax counter and ajax update panel in asp.net but it is taking so much time to load all counters and to run those counters. You can see my created website at : www.vif-tech.com/BidsOnline

Can anyone suggest me any good server side counter than ajax counter which can run fast or if I u开发者_开发百科se a simple javascript counter, how can I bind it with database ?

Awaiting your help guys .. Thanks in advance

Using fiddler, I can tell they are making ajax calls in php every 1 second to get the latest bid info for all the bids. They are pretty small calls..about 200 bytes each, so it's fast.

The ajax calls on your page are about 70kb every 1 second, making it very slow & and heavy on your server when you have a dozen users at once.

Download fiddler and run it while using your page. Then try to get that request size down.
