Nothing accumulates. The Director spawns and despawns as it goes, the map is loaded once, and a round reset returns the server to where it started. That makes this one of the few games here where the figure you size for on day one is still correct months later.
The mistake to avoid
Over-provisioning. Extra memory buys nothing on a stock server — if it stutters, the cause is network latency or custom content loading, not capacity. Spend on a location close to your players instead.
