Regarding Performance: Good Example Site Using AJAX Toolkit?

Hi guys,

Could anyone point me to any good examples of sites using AJAX Toolkit effects that give good performance?

To be clear, it’s ‘not’ visual inspiration I’m after so much - but the number of extenders/effects that can be used without a performance degradation.

So, a site giving a good example of the number of extenders possible still with good performance.

Thanks very much indeed, I really appreciate any help :)

Dan :)
