Satisfactory Server Performance Optimization Guide

Optimize your Satisfactory server performance to handle massive factories without lag or frame drops. This comprehensive guide covers server configuration, factory design optimization, and hardware tuning to ensure smooth multiplayer factory building experiences. Large-scale factories can strain server resources, but proper optimization keeps your Satisfactory server running smoothly even with complex automated production lines.

​
Server Configuration Optimization

​
Basic Performance Settings

Edit GameUserSettings.ini for optimal performance: 
[/Script/FactoryGame.FGServerSubsystem]
mAutoPause=True
mAutoSaveOnDisconnect=True
mAutoSaveInterval=600
mNetworkQuality=3
mServerRestartTimeSlot=04:00
Key Settings Explained:
  • mAutoPause=True - Pauses server when no players online
  • mAutoSaveInterval=600 - Save every 10 minutes (reduce for stability)
  • mNetworkQuality=3 - Maximum network quality for smooth multiplayer
  • mServerRestartTimeSlot - Daily restart during low-activity hours

​
Advanced Server Parameters

Startup Parameters for Performance: 
-USEALLAVAILABLECORES -NoVerifyGC -NoAsyncLoadingThread -UseMultithreadForDS
Memory Management: 
-Xmx16G -Xms8G -XX:+UseG1GC -XX:MaxGCPauseMillis=50

​
Network Optimization

Reduce network lag with these settings: 
[/Script/Engine.GameNetworkManager]
TotalNetBandwidth=32000
MaxDynamicBandwidth=16000
MinDynamicBandwidth=4000
Connection Quality Settings:
  • Increase bandwidth limits for better multiplayer experience
  • Adjust based on server internet connection capacity
  • Monitor network usage during peak factory operation

​
Factory Design Optimization

​
Conveyor Belt Optimization

Reduce belt-related lag:

​
Belt Density Management

  • Limit belt crossings - Avoid complex belt intersections
  • Use vertical space - Stack belts instead of spreading horizontally
  • Minimize belt length - Shorter belts = better performance
  • Avoid unnecessary splitters - Direct routing when possible

​
Smart Belt Design

Good: Direct belt routing
[Miner] → [Belt] → [Constructor] → [Belt] → [Storage]

Avoid: Excessive splitting
[Miner] → [Splitter] → [Splitter] → [Merger] → [Constructor]

​
Machine Placement Optimization

Efficient factory layouts:

​
Centralized Production

  • Group similar machines together
  • Minimize pipe/belt distances between machines
  • Use local storage for intermediate products
  • Batch production instead of continuous streams

​
Power Distribution

  • Central power spine with branch distribution
  • Avoid long power lines across the map
  • Use power switches to disable unused factory sections
  • Monitor power consumption and optimize generators

​
Building Optimization

Reduce rendering load:

​
Foundation Usage

  • Use minimal foundations - Only where necessary
  • Avoid decorative foundations in hidden areas
  • Group foundation placement for efficiency
  • Remove unused foundations regularly

​
Wall and Structure Optimization

  • Limit decorative walls in large factories
  • Use simple wall designs over complex patterns
  • Avoid excessive lighting in automated areas
  • Remove unnecessary structural elements

​
Hardware and System Optimization

​
Server Hardware Requirements

Recommended specifications for large factories:
Factory SizeCPURAMStorage
Small (1-2 players)4 cores8GB20GB SSD
Medium (3-4 players)6 cores16GB40GB NVMe
Large (Complex factories)8+ cores32GB60GB+ NVMe

​
Memory Management

Optimize RAM usage:

​
Server Memory Settings

[SystemSettings]
r.Streaming.PoolSize=2048
r.Streaming.MaxTempMemoryAllowed=256

​
Garbage Collection

  • Enable auto-pause when server empty
  • Regular server restarts (daily recommended)
  • Monitor memory usage trends
  • Clear cache files periodically

​
Storage Optimization

Improve I/O performance:

​
Save File Management

  • Regular save cleanup - Remove old autosaves
  • Compress save files when backing up
  • Use SSD storage for server files
  • Monitor disk space usage

​
File System Optimization

# Linux optimization
echo 'vm.swappiness=10' >> /etc/sysctl.conf
echo 'vm.vfs_cache_pressure=50' >> /etc/sysctl.conf

​
Factory Performance Monitoring

​
Performance Metrics to Track

Key indicators of factory performance:

​
Server Metrics

  • Server FPS - Target: 30+ FPS
  • Memory usage - Should not exceed 80%
  • CPU utilization - Monitor during peak hours
  • Network latency - Keep under 100ms

​
Factory Metrics

  • Machine efficiency - Identify bottlenecks
  • Power consumption - Optimize generator usage
  • Belt throughput - Monitor item flow rates
  • Production rates - Track output efficiency

​
Monitoring Tools

Built-in Performance Tools:
  • Press Ctrl + Shift + L for performance overlay
  • Use console command stat fps for FPS display
  • Monitor task manager for resource usage
  • Check server logs for performance warnings

​
Common Performance Issues

​
Factory Lag Solutions

Symptoms and fixes:

​
Low Server FPS

Causes:
  • Too many active machines
  • Complex belt networks
  • Excessive decorative elements
Solutions:
  1. Reduce active machines - Use power switches
  2. Simplify belt routing - Direct paths preferred
  3. Remove decorations in automated areas
  4. Implement factory zones - Separate production areas

​
Memory Leaks

Symptoms:
  • Gradually increasing RAM usage
  • Server becomes unresponsive
  • Frequent crashes during gameplay
Solutions:
  1. Regular server restarts - Daily recommended
  2. Clear save file cache - Remove temporary files
  3. Monitor mod memory usage - Disable problematic mods
  4. Upgrade server RAM - If consistently high usage

​
Network Performance Issues

Multiplayer lag solutions:

​
High Ping/Latency

Optimization steps:
  1. Choose closer server location - Reduce physical distance
  2. Optimize network settings - Increase bandwidth limits
  3. Use wired connections - Ethernet over WiFi
  4. Limit background applications - Close bandwidth-heavy programs

​
Desync Issues

Synchronization problems:
  1. Ensure stable connections - All players
  2. Coordinate building times - Avoid simultaneous construction
  3. Regular save/reload - Resync server state
  4. Monitor packet loss - Check connection quality

​
Optimization Best Practices

​
Factory Planning

Design for performance from the start:

​
Modular Design

  • Separate production areas by function
  • Use local storage for each module
  • Implement power zones with switches
  • Plan expansion areas in advance

​
Efficient Layouts

  • Minimize transport distances between production stages
  • Use vertical building to save horizontal space
  • Group similar machines for easier management
  • Plan belt routing before building

​
Maintenance Schedule

Regular optimization tasks:

​
Daily Tasks

  • Monitor server performance metrics
  • Check for error messages in logs
