A Satisfactory dedicated server needs 8 GB of memory to start with, 16 GB for a big save or for more than 4 players, a processor with fast single-core speed, and a few GB of disk. Those figures are the community advice for a server you run yourself. Your Loafhosts server shows how much memory it uses against its limit in Memory Load at the top of its page. A new empty world uses about 3 GB of memory and about 3 GB of disk. A big factory needs much more than that.
The community figures
These come from the official wiki. It calls them “community recommendations for minimum requirements”, and says the server “may or may not run with less powerful hardware, depending on player count and save file size.”
| Part | What the wiki says |
|---|---|
| Processor | Intel i5-3570 or better, or AMD Ryzen 5 3600 or better. Details below the table. |
| Memory | 8 GB. 16 GB “may be recommended for larger saves or to host more than 4 players”. |
| Disk | Server files of 12.4 GB on Windows. On Linux, 8 GB including the operating system. |
| Virtual machines | A kvm64 processor type does not work. Use the host processor type. |
The processor, in the wiki’s words:
- A fairly recent x86-64 processor. No 32-bit and no ARM.
- The server uses several cores but “heavily favors high single-core performance”.
- A single-thread rating of 2000 or more should work.
The disk figures differ by system. Use the measured numbers below for a Loafhosts server.
What a Loafhosts server uses
Measured on Loafhosts servers on 27 October 2026:
- Disk: the install is about 3 GB, plus saves and any mods.
- Memory: about 3 GB with a new world and nobody on. It grows with the size of the factory, the number of players and the mods you add.
- Start: the game is ready a few seconds after the server starts, once it is installed.
Mods and big factories need more. A factory that has grown for many hours is bigger every hour, and the server has to move all of it on every tick.
How to tell if the server keeps up
The game runs the factory in small steps called ticks. Full speed is 30 ticks a second. If the server cannot keep that up, machines run slow for everyone, whatever each player’s own computer does.
Open the Server page and look at the card Tick rate. It draws the last two days. Its help line says “How often a second the server moves the factory on, over the last two days. 30 is full speed.” Above the graph are the readings Now and Lowest. Below it is a line that says whether the server kept up.
- “Full speed.” means the server is keeping up.
- “The factory has run slow.” means it fell behind at some point. Big factories slow the server down. A daily restart helps, and so does a lower network quality with many players.
- “The factory runs slow now.” means it is behind right now. A restart helps at once.
The card also shows the size of the newest save: “the bigger the factory, the more the server has to move each tick.”
- Tick rate
- Now and lowest
The panel reads the tick rate once a minute while the game runs, so a server that was just started shows “No readings yet”.
If the server is too small
- Out of memory: the Crashes page shows how each start ended and why. See Satisfactory out of memory.
- Lag with many players: lower Players on Startup (see max players), lower Network quality on the Server page, or restart every day.
- A very large save: the Tick rate card will show it. The remedy is a server with more memory and a faster core.
