WoW Mathematics: Server Loading

Hosts of MMORPGs face several dilemmas regarding the servers they operate. One of these, by far a significant one, is the maximum capacity the servers are able to take. Too low a capacity and players will complain about latency and other performance problems, while too high a capacity and the investment in the hardware will not be cost-effective. This problem is exacerbated by the tendency of the load to change cyclically throughout the day.

Deciding on the servers' capabilities is not a simple matter of allowing for a specific number of players. As the mathematics that follows shows, the throughput load created by those players will change according to the tendency of players to cluster together in the game world.
