Lag and stuttering can ruin the player experience on your Rust server. At Imperium Hosting, we offer high-performance infrastructure — but server-side performance tuning still plays a key role in delivering smooth gameplay.
This guide will walk you through practical ways to optimize your Rust server, reduce performance issues, and improve player retention.
Key Performance Considerations
1. Server Hardware
All Imperium Hosting Rust servers run on enterprise-grade hardware with SSD/NVMe storage, eliminating common bottlenecks. However, if you're still seeing lag, other factors may be at play.
2. Rust Updates & Patch Impact
Frequent game updates from Facepunch may temporarily degrade server performance. If issues arise after a patch, check Rust community forums or changelogs for known issues.
3. Network Stability
We operate in low-latency data centers with full DDoS protection, ensuring your server is stable and resilient to attacks. Still, choosing the right data center location for your audience is critical.
4. Entity & Collider Overload
Every object on your map — bases, loot, vehicles, even sleeping bags — is an entity. The more entities and colliders present, the heavier the load on your server. Regular map wipes and encouraging base decay help.
5. Plugins & uMod/Oxide
Mods via uMod/Oxide can be performance-friendly if well written. One poorly coded plugin can tank your entire server. Use performance monitoring tools (below) to pinpoint and remove offending plugins.
Monitoring Server Performance
Check Server FPS
Use the fps command in your Web Console (RCON) to see server-side framerate. 30–60 FPS is generally fine.
Enable Garbage Collection Warnings
Run the following command via RCON to monitor garbage collection slowdowns:
Warnings over 2 seconds should be investigated.
Use Performance Monitor (uMod Plugin)
The Performance Monitor plugin shows:
-
Memory usage
-
Hook timings
-
Plugin performance
Don’t leave it enabled long-term, as it adds overhead.
Optimization Techniques
Remove Resource-Heavy Plugins
Use performance monitoring tools to identify and remove poorly optimized plugins. Fewer plugins = better performance.
Limit Server FPS
Cap server FPS using:
Facepunch recommends 30–60 FPS for most servers. Higher values offer no gameplay benefit and consume unnecessary CPU.
Disable AI Thinking
Reduce animal/AI overhead with:
Commonly used on high-pop servers to reduce lag from NPC movement.
Increase Save Interval
Reduce stutters by increasing how often the server saves data:
(A value of 600 means the server saves every 10 minutes)
Tweak Upkeep Settings
Faster base decay reduces unused entities. Use decay.upkeep_period_minutes and other related settings.
Daily Server Restarts
A daily reboot can help clear memory leaks or plugin-related bloat on modded servers. Automate this using a scheduled task in your TCAdmin control panel.
Final Tips
-
Use smaller maps for better performance on lower-pop servers.
-
Encourage players to clean up unused builds.
-
Regularly wipe or soft-wipe servers to control entity count.
-
Monitor logs and plugin performance weekly.
