A URL to something that shows the problem really would be useful here. I can profile and all that, but it would be good to be profiling something that actually shows the problem.
Tell ya what, give me a few hours to unwind from my gig this morning and I'll see if I can't get my old server actually up and online and port-forwarded. If I can (this assumes I actually have spare ports on the router) I'll send you the link, as I see that No-IP just sent me a renewal notice for the game's domain name anyways.
