FerrumC is a re-implementation of a server for the game Minecraft (version 1.21.8) built from scratch in Rust, designed to offer significantly improved performance and memory efficiency compared to vanilla server implementations. By using Rust’s concurrency and safety guarantees, FerrumC runs fully multithreaded, allowing it to utilize all available CPU cores — which helps deliver smoother, low-latency, high-throughput multiplayer experiences. The project aims both at providing a fast, lean server for typical use (friends or small communities) and offering a foundation that could support large-scale servers, mod/plugin systems, and custom server configurations. FerrumC supports importing existing Minecraft worlds, making it easy for users to migrate from standard servers without losing progress. Its networking, world encoding (chunks, NBT, Anvil format), and entity systems are custom-built with efficiency in mind, which results in fast world loading, minimal I/O lag.
Features
- Fully multithreaded server architecture using Rust for high performance and concurrency
- Compatible with vanilla Minecraft clients (version 1.21.8)
- Ability to import existing worlds from standard Minecraft installs
- Efficient, custom-built encoding/decoding for chunks, NBT, and Anvil formats to reduce I/O lag
- Memory-efficient world loading and runtime, aiming for minimal resource consumption
- Customizable server list and configuration to run small private servers or scale up
