What an idle server uses
| What | Measured |
|---|---|
| RAM with the world loaded and nobody on | 10.6 GB (10.2 GB at load, flat for 9 hours) |
| CPU idle | a third of a core (the server idles at 5 ticks a second) |
| Install | 15.5 GB, plus about 0.5 GB for the Wine prefix on Linux |
| Time to load the island | about 90 seconds on 4 cores |
| Stopping it | 3.3 seconds |
Tip:Memory and CPU grow with the crowd, so the plans below are sized with room above the idle figure, and a busy server wants the next plan up. For comparison, on 2026-10-29 other SCUM hosts sold 12 GB at $23.99, 16 GB at $31.99 and 24 GB at $47.99 (Game Host Bros), and 10 GB at $12.99, 14 GB at $18.99, 18 GB at $24.99 and 22 GB at $29.99 (Cybrancee).
Ports
| Port | Number | Protocol | What for |
|---|---|---|---|
| -port (game) | 7777 | UDP | Game traffic: what players join on |
| game port + 2 | 7779 | TCP | The game's own info responder (measured: the only other socket the loaded server opens) |
The server binds the game port you give it with -port= and uses that port plus two. It answers no Steam query on any port. On Flux the three ports 7777, 7778 and 7779 are published as one block, and the block is moved together.

A plan's player count is where Max Players starts, not a cap: you can set a higher number.
