Memory and CPU
The 64-bit server idles at about 700 MB on ctf_2fort with SourceMod loaded. Players, bots, plugins and big custom maps add to it. The game's simulation runs on one thread at 66 ticks a second, so a fast core matters more than core count.
| Players | Typical use | RAM | CPU |
|---|---|---|---|
| Up to 12 | 6 v 6 competitive, or a group of friends | 2 GB | 1.5 vCores |
| Up to 24 | A classic 12 v 12 public server | 3 GB | 2 vCores |
| Up to 32 | 16 v 16 with SourceMod plugins | 4 GB | 2.5 vCores |
Disk
The server is about 15 GB once installed, with all 238 official maps. Custom and Workshop maps, plugins and logs come on top. Fast local storage matters: the server reads the game's files at every map change.
Network
- One port, 27015 by default: UDP for the game and the Steam query, TCP for RCON when you turn it on (it is off without an RCON password).
- About 30 to 60 KB/s per player at the default rates.
- A Game Server Login Token (App ID 440) to be listed in the server browser.
