A Loafhosts Factorio server comes in three sizes. Small has 2 cores, 3 GB of memory and 20 GB of disk, and is sized for 10 players. Standard has 2 cores, 4 GB and 20 GB, for 20 players. Large has 4 cores, 6 GB and 30 GB, for 40 players. A bigger factory or more mods need more memory than the player count suggests.
The three sizes
| Size | Cores | Memory | Disk | Players |
|---|---|---|---|---|
| Small | 2 | 3 GB | 20 GB | 10 |
| Standard | 2 | 4 GB | 20 GB | 20 |
| Large | 4 | 6 GB | 30 GB | 40 |
The panel shows memory and disk a little higher than the plan’s size, so a 4 GB plan reads about 4.3 GB. A bigger plan can be chosen later from the account’s billing pages.
What the player number means
The player number is what the size is meant for. It is not a limit that the game enforces. A new server starts with Most players set to 0, which means no limit, and admins can always join a full server. To set a limit, change Most players under Joining in the Config Editor. It applies at once. See change the player limit.
What uses memory
Factorio keeps the whole map and every machine in memory. A few things make it grow:
- A bigger factory. Every belt, inserter and machine is held in memory, so the world grows with the factory, not with the number of players.
- Mods. Each mod adds items, recipes and scripts. Wube’s own Space Age mods are on by default on a new server and add planets.
- More explored map. Chunks the game has made stay in the save.
The disk holds the game, the saves, the autosaves and the logs. A big world with several autosave files takes more disk. The autosave count is Autosaves kept in the Config Editor, and a world can be removed on the World page.
See how much the server uses
Open the Console page while the server is running. The strip of live readings there shows its memory use against the size of the plan. Watch it with the players on, not with an empty server. If memory stays close to the limit, the server will run out of memory. Start on the size you have, and move to a bigger plan if that happens.
When it runs out of memory
The game stops when it has no memory left. When the machine ends the server for memory, Crashes shows Crashed, Out of memory Yes and “The server used all its memory and was stopped”. Big factories and big mods need more. Remove a mod you do not need, or raise the server’s memory. A bigger plan is the second choice. Removing mods is on the Mods page and applies at the next start.
Not checked on 2.1.24 as of 13 November 2026: how much memory a large Space Age factory uses with a full player list. The sizes above are the plans, not a promise for a given world.
If it does not work
- The server is slow with many players. See Factorio server lag.
- The server keeps stopping. Open Crashes. If it says it ran out of memory, see out of memory.
