faster server, and better server side code. database optimazation, caching results, etc. Make split some long operations somehow into 2. Most of my app time goes to figuring out how to make it more optimized now for this reason. My Dual Xeon Quad was at 100% when I put it online a week ago. Now it went down but still if I going ot get more users on my app, I will need to have my app alot more optimized code for my apps. Early design is really important, for things are you going to have JSON webservice for one thing or XML for the other, and tag names can be purposely small to descrease bytes sent.
