Performance Optimization Guide
CPU Optimization
🎯 Core Allocation
Assign dedicated cores for StarRupture server processes. Avoid sharing cores with other intensive applications.
⚡ CPU Governor
On Linux, use "performance" CPU governor. On Windows, set power plan to "High Performance" for consistent clock speeds.
📊 Priority Management
Set server process to "High" priority in Windows Task Manager or use "nice -n -10" on Linux.
Memory Management
| Player Count | Base RAM | Factory RAM | Total Recommended |
|---|---|---|---|
| 2 Players | 4 GB | 2-3 GB | 8 GB minimum, 12 GB optimal |
| 3 Players | 5 GB | 3-4 GB | 12 GB minimum, 16 GB optimal |
| 4 Players | 6 GB | 4-6 GB | 16 GB minimum, 24 GB optimal |
Note: Factory automation systems consume significant memory as production chains grow. Plan for 25-50% extra RAM for complex factory designs.
Storage Requirements & Optimization
World Save Growth Patterns
| Game Phase | Save File Size | Growth Rate | Backup Frequency |
|---|---|---|---|
| Early Game | 100-500 MB | Slow | Daily |
| Mid Game | 500 MB - 2 GB | Moderate | Every 6 hours |
| Late Game | 2-5 GB | Fast | Every 2 hours |
| Mega Factory | 5-10+ GB | Very Fast | Hourly |
Storage Optimization Tips
- NVMe SSDs: Essential for large factory worlds with frequent autosaves
- Separate Partitions: Isolate game files from OS for better performance
- Backup Strategy: Implement incremental backups to manage save file growth
- Trim Support: Ensure TRIM is enabled on SSDs for longevity
Network Configuration
Bandwidth Requirements
| Player Count | Upload Speed | Download Speed | Latency Target |
|---|---|---|---|
| 2 Players | 5-10 Mbps | 25 Mbps | < 50 ms |
| 3 Players | 10-20 Mbps | 50 Mbps | < 40 ms |
| 4 Players | 20-30 Mbps | 100 Mbps | < 30 ms |
Port Configuration
🎮 Game Port
27015 UDP - Primary game communication. Must be open for player connections.
🔍 Query Port
27016 UDP - Server browser visibility. Optional but recommended.
🔄 RCON Port
27020 TCP - Remote administration. Optional for advanced management.
Monitoring & Maintenance
Key Performance Metrics
| Metric | Healthy Range | Warning Threshold | Critical Threshold |
|---|---|---|---|
| CPU Usage | 40-70% | 80% | 90% |
| RAM Usage | 60-80% | 85% | 90% |
| Network Latency | < 50 ms | 100 ms | 200 ms |
| Disk I/O | < 50 MB/s | 100 MB/s | 200 MB/s |
Automated Monitoring Setup
- Performance Counters: Track CPU, RAM, disk, and network metrics
- Log Monitoring: Monitor server logs for errors and warnings
- Alert System: Set up email/SMS alerts for critical thresholds
- Dashboard: Create performance dashboard with Grafana or similar tools
Scaling Considerations
Factory Complexity Impact
🏭 Simple Factories
Basic production chains: Minimal performance impact. Follow minimum requirements.
⚙️ Complex Factories
Advanced automation: Moderate CPU/RAM increase. Add 25% to recommended specs.
🌉 Mega Factories
Massive production networks: Significant resource demands. Double recommended specs.
Player Activity Patterns
| Activity Type | CPU Impact | RAM Impact | Network Impact |
|---|---|---|---|
| Exploration | Low | Low | Medium |
| Base Building | Medium | Medium | Low |
| Factory Operation | High | High | Medium |
| Combat Events | Medium | Medium | High |
Troubleshooting Performance Issues
⚡ High CPU Usage
Limit factory complexity, reduce entity counts, optimize production chains, and consider CPU upgrade.
💾 High Memory Usage
Increase RAM, optimize save files, reduce chunk loading distance, implement regular restarts.
🌐 Network Lag
Upgrade bandwidth, optimize router QoS settings, reduce player count, or move server closer to players.
💽 Disk I/O Bottlenecks
Upgrade to NVMe SSD, reduce autosave frequency, implement RAM caching, or use RAID configurations.
Future-Proofing Your Server
Expected Growth Patterns
- Early Access Updates: Game updates may increase resource requirements by 20-30%
- Content Expansion: DLCs and expansions could add new biomes and factory components
- Mod Support: Community mods may significantly increase resource demands
- Player Limit Increases: Future updates may expand beyond 4-player limit
Recommended Hardware Upgrades
| Upgrade Priority | Component | Benefit | Estimated Cost |
|---|---|---|---|
| 1. Storage | NVMe SSD | Faster world saves, reduced lag | $$ |
| 2. RAM | 32 GB DDR4/5 | Handles complex factories, future-proof | $$$ |
| 3. CPU | 8+ core processor | Better multitasking, handles updates | $$$$ |
| 4. Network | Gigabit connection | Supports more players, lower latency | $$-$$$ |
Pro Tip: Start with recommended specs and monitor performance. Scale up gradually based on actual usage patterns and factory complexity rather than over-provisioning from day one.
