I agree about latency and have tested for that all the way to Europe and Asia. I did find a latency of 31ms from my server to over 700 miles. I think the worst I saw was still under 1 second. Since my packet size typcally is under 1500 bytes 31msec is very much not an issue at this point but the number requests at the server is my focus.
