If you've ever tried running a Rust server on an underpowered VPS, you know the pain of entity desync and out-of-memory crashes. Rust is a beast—it simulates physics, AI, and building decay simultaneously. A fresh 3km map eats ~2GB of RAM, and after a few days of active raiding, you're easily pushing 12GB.
Here is a technical overview of how we provision bare-metal boxes at Fit Servers to run Rust perfectly.
- The Bare-Metal Hardware Rust's main thread is heavily single-threaded. You need high clock speeds. We recommend:
CPU: Ryzen 5800X3D or i9-11900K
RAM: 24–32 GB (essential for 100+ players)
Storage: NVMe SSDs (critical for fast world saving without stuttering)
OS: Ubuntu 22.04 LTS or 24.04 LTS
Oxide Plugins & uMod
Vanilla Rust is great, but community servers thrive on plugins. By pulling the latest Linux build of Oxide (Oxide-Rust_Linux.zip), you can drop .cs files directly into oxide/plugins/ to hot-load modifications like BetterChat or GatherManager without restarting the daemon.Automating Wipes with Cron
Facepunch forces a wipe on the first Thursday of every month. We automate this by triggering a shell script via cron that warns players via RCON, gracefuly stops the server, randomizes the server.seed, deletes .sav files, updates via SteamCMD, and spins the tmux session back up.
