Rust server performance depends mostly on map size, player count, plugins and how much has been built since the last wipe. On a FREAKHOSTING server, keep Map size and Player slots in Server settings in line with your memory, leave Save interval at a sensible value, check plugins for errors, wipe regularly and restart daily with Schedules. Watch memory and CPU on Statistics.

​
What uses memory on a Rust server?

  • Map size. The panel warns: “Bigger maps need a lot more memory.” Facepunch also notes that larger maps need more disk space and memory. A 3000 map used about 4.9 GB on our test server before anyone joined.
  • Players. “More players need more memory,” and more players need a faster CPU.
  • Buildings and entities. Every base, box and deployable is saved and simulated. The world grows during a wipe and shrinks again when you wipe.
  • Plugins. Each Oxide or Carbon plugin adds work. A broken plugin can spam errors.

​
How to check your server’s load

Open Statistics for memory, CPU and network use. Set up server alerts to get a message by e-mail, Discord or webhook when the server crashes or its memory stays at the limit. In the Console, status shows each player’s ping.

How to make your Rust server run better

1

Pick a map size that fits

In Server settings, keep Map size modest for small groups. A smaller map also starts faster. A new size means a new map; see map seed and size.
2

Match player slots to your plan

Set Player slots to the number of players you really expect.
3

Keep the save interval sensible

Save interval is 60 seconds by default. The panel explains: “Short intervals lose less after a crash but can cause small lag spikes.” Avoid very short intervals on large maps.
4

Check your plugins

On Plugins, switch off plugins you don’t use. Read the console after a restart for compile errors and repeated warnings.
5

Keep decay on

In Server settings, Decay speed 0 turns decay off, so abandoned bases never disappear and the world keeps growing. Leave it at 1, or lower it only a little.
6

Restart daily

A daily restart gives a fresh start. Set one up in Schedules; see wipe schedules and restarts.
7

Wipe regularly

A wipe removes every building and entity. Many servers wipe weekly or every two weeks; every server wipes at the monthly forced wipe.

Is the lag on the server or on the player’s side?

Frequently asked questions

​
How much RAM does a Rust server need?

It depends on map size, players and plugins. Our test server used about 4.9 GB after start-up on a 3000 map with no players. Bigger maps, more players and more buildings need more.

​
Why does my Rust server take so long to start?

The first start generates the map, about 5 to 6 minutes on a 3000 map. Later starts load the saved map and are faster. Big maps and many plugins take longer.

​
Does a bigger map lag more?

A bigger map needs more memory and takes longer to generate and save. Choose the smallest size that suits your player count.

​
Should I restart my Rust server every day?

A daily restart is a common habit and keeps memory use in check. Schedule it at a quiet time and warn players first.
