Memory and CPU
An empty server sleeps (it hibernates when nobody is on) at about 1.1 GB of RAM and 3 % of one core. With 15 bots awake and six plugins loaded it used 1.3 GB and about a quarter of a core. We have not measured a full 64-player server, so the plans size memory and cores with room to spare rather than to a measured limit.
| Plan (starting players) | Typical use | RAM | CPU |
|---|---|---|---|
| 10 Players | Scrims, retakes, a small community | 3 GB | 2 vCores |
| 24 Players | A busy community server with plugins | 4.5 GB | 3 vCores |
| 64 Players | Full 64-player servers | 6 GB | 4 vCores |
Disk
The game is about 70 GB installed and a 73 GB download. Game updates, Workshop maps, plugins and logs come on top, so the plans have 100 to 120 GB. 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).
- A Game Server Login Token (App ID 730) to be listed in the community server browser.
- A fast connection for the first install: 73 GB takes about an hour and a half at 100 Mbit/s.
