What uses the memory in Sons of the Forest
Cannibal and mutant AI is simulated across the whole map all the time, following factions and behaviour instead of spawning and despawning near players. The terrain can be changed and player buildings persist on top of that. The upshot is a server whose cost is almost all world simulation, with the eight slots adding very little.

Where people get it wrong
Taking the eight-player limit as a sign the server can be small. Group size is close to meaningless for sizing Sons of the Forest; what you are paying for is the always-on world simulation plus whatever gets built.
