Improve Valheim Server Performance

A well-optimized Valheim server ensures smooth gameplay, stable FPS, fewer lag spikes, and a better overall experience. Large bases and heavy building activity are the main performance factors.

---

Basic Performance Tips

• Restart the server regularly (recommended every 4–6 hours)
• Avoid excessively large bases
• Reduce unnecessary structures and items
• Keep the server up to date

---

Optimize Server Settings

1. Limit Player Count

More players increase physics, building, and world simulation load.

maxplayers=10-16 (recommended for stable performance)

Tip: Start small and only increase once performance is stable.

---

Reduce World and Base Load

• Avoid extremely large bases
• Reduce decorative objects
• Separate large building projects into different areas
• Be careful with modded systems that add automation or physics load

---

Hardware Optimization

• CPU: Very important (high single-core performance required)
• RAM: 8 GB minimum, 16 GB recommended
• Storage: NVMe SSD recommended for fast world saves

---

Network Optimization

• Stable connection with no packet loss
• Low latency for better synchronization
• DDoS protection recommended

---

Server Configuration Optimization

1. Save Interval Considerations

Frequent saves can cause short lag spikes. If possible, optimize save intervals.

2. World Load Reduction

Valheim permanently stores all built structures, so the more players build, the heavier the world becomes.

---

Common Performance Issues

Lag Spikes

• Large bases with many objects
• Many players in one area
• Autosave causing brief stutters

Stuttering / Delays

• CPU overload
• Too many physics-heavy objects

Desync Issues

• Unstable network connection
• Server overload

---

Best Practices

• Adjust player count to hardware capacity
• Restart the server regularly
• Avoid or split large bases
• Use NVMe SSDs for faster save performance

---

Conclusion

Valheim server performance is mainly limited by CPU power and base size. With proper configuration and regular maintenance, stability can be significantly improved.
