If you have to use javascript, then use a faster machine than what I am using. Mine does not hesitate much on the banners but it does happen. But it is a result of the old machine, not enough memory and bandwidth issues. I also store 100% of all of the banners and serve them directly. So I once in a while hit my peak max on the line for that instance. Going to increase my bandwidth, so that may even fix that along with the newer server.
