Rust 2026 Multithreaded Networking Fix for Dedicated Server

Rust Guide • Updated Feb 21, 2026

Rust 2026 Multithreaded Networking Fix for Dedicated Server

For years, Rust dedicated servers were bottlenecked by single-core networking throughput. In 2026, Facepunch officially introduced Multithreaded Networking (MT-Net) to the server binary. While this can increase your server's TPS (Ticks Per Second) by up to 30%, it requires specific configuration to prevent "Thread Starvation" during peak raid hours. This guide covers the optimal setup for MT-Net.

🧵 Parallel Packet Processing

Instead of one core handling all 300 players, MT-Net distributes player data across all available CPU threads, reducing "Net-Stutter" during large PVP fights.

⚡ The TPS Ceiling

Vanilla Rust aims for 10 TPS, but with MT-Net, you can reliably push to 30 or 60 TPS, making weapon recoil and movement feel vastly more responsive.

How to Enable Multithreaded Networking

Ensure your Rust dedicated server is running the latest 2026 build. Add these variables to your startup command line (-server.net_threading 1) or your server.cfg:

# Enable Multithreading
server.net_threading 1
server.net_thread_count 4
server.net_priority_workers 2

Optimizing Thread Count

Setting server.net_thread_count too high can actually hurt performance due to context switching. A good rule of thumb is:

  • 4-8 Cores: Set to 2.
  • 16+ Cores: Set to 4 or 6.
  • Never exceed half of your physical core count.

Common MT-Net Issues

If you see [Networking] Thread Starvation Warning in your console, it means your workers are being blocked by another intensive task (like world serialization or plugin logic). To fix this:

  1. Increase server.net_priority_workers to ensure networking packets always have a dedicated core.
  2. Disable heavy analytic plugins that hook into OnPlayerMove.
  3. If using Oxide/uMod, ensure your plugins are compatible with the new threaded hooks.

Expert Tip: For the absolute best networking performance, host your server on Supercraft. Our 2026 hardware is specifically tuned for Rust's MT-Net architecture with optimized kernel-level packet handling.

Experience the future of Rust. Take your server to 60 TPS and leave the lag behind.
