Nexon's decline in traffic

I left out that even an empty map no one can reach is still a drain on resources because in addition to the memory it occupies, it also takes a bit of CPU for the main loop to stop in and poll that map for any pending events each tick. It's not much, but it does add up when you're talking hundreds of maps across multiple channels.

An event handler with lazy loading would be enough to solve that issue. If no events have ever been reported, then that place should never be polled. Only load the resource if an event is reported from that resource. See? Client side programming is better!. (snark)
