nah the animation processing is all done on your browser rather than the server, the server just has to deliver the file to your browser. I'm not quite sure what it is to be honest, as it's working very fast now when it's been much slower with less users. I've got a professional in to help me as well. I'm talking to the server people about doubling the amount of RAM and getting a faster CPU on board which surely should be enough, it's about 30% more expensive but theres no point in forking out the 70% if the thing is going down all the time.
