What uses the memory in Left 4 Dead 2
Nothing builds up. The Director spawns and removes things as it goes, the map loads once, and each round reset puts the server back where it started. That makes it one of the few games here where your day-one figure is still right months later.

Where people get it wrong
Paying for headroom you will never use. More memory does nothing for a stock server; stutter there comes from network latency or custom content loading. Put the budget into a server located near your players.
