Satisfactory is unusual among game servers: player count barely affects server load. What destroys performance is factory complexity - belt networks, drones, power grids, and train routes all run server-side. A small factory with 4 players needs less resources than a mega-factory solo.
Hardware Scaling by Factory Stage
| Factory Stage | RAM | CPU |
|---|---|---|
| Early game / exploration | 4 GB | 2 cores |
| Mid-game factory (mk2 - mk4 belts) | 8 GB | 4 cores |
| Late game / nuclear + trains | 16 GB | 4 cores |
| End-game megalith | 32 GB | 6 cores |
Plan your VPS size for where players will be in 3 months, not day 1.

Managing Save Files
Satisfactory saves are large and should be backed up regularly:
# Backup location
/home/satisfactory/.config/Epic/FactoryGame/Saved/SaveGames/server/
# Automated daily backup
0 3 * * * tar -czf /backups/satisFactory-$(date +%Y%m%d).tar.gz /home/satisfactory/.config/Epic/FactoryGame/Saved/
Performance Tuning
For large factories:
- Increase
MaxNetworkBandwidthin Game.ini to prevent desync on complex factory visualisation - Use Pause Game on disconnect to prevent the factory from running calculations when no players are online
- Monitor CPU single-thread performance - Satisfactory is largely single-threaded
