Personally, I'm not sure whether this is limited to click events. For the reason that the more and more elements you add, the slower scrolling and re-draws become. If you do a hard scroll down the page, all you see is the background colour and then the components appear after some time. This, as well as the click event issue, becomes worse as you increase the number of items on the page. Unless the click event is somehow causing that too.

Thanks,
