How the login queues work on a server with a stable population: You go to log in. You are number 29 in queue. You wait a minute. You are logged in.

How the login queues work on a server with a large population that is paranoid about login queues: You go to log in. You are 1,029 in queue. There are 6,000 people already on the server, of which 2000+ are using the crafting cheat to stay logged inn past the 30 minute auto disconnect. The other 4000 are playing. Occasionally one disconnects and a spot opens up. The queue crawls.

SE handled this at 4.0 launch by implementing a 24 hour mass logout because the same thing happened on Balmung server. Their servers get unstable beyond 5000-7000 active connections per world. Upgraded hardware won't fix it; it's a core problem at the database level, I suspect.
