How much RAM does a Rust server need?

Q: How much RAM does a Rust server need?

About 11 GB for 20 players without mods, and never less than 8 GB. Rust is one of the heaviest servers to run: memory grows with map size, entities and the days since the last wipe. This is an estimate based on typical usage.

How this estimate works

We start from Rust’s published server requirements (at least 8 GB), then add memory for each player, each of your Oxide/Carbon plugins and your map size, and round up to a whole GB. It’s an estimate based on typical usage: a world that has been played for a long time, or heavy mods, can need more. Source for the minimum.
