Rust Server Hardware Requirements
Understanding hardware needs for running a stable Rust server based on your player count and configuration.
Minimum Requirements
For small servers (10-20 players) with vanilla setup:
- CPU: 4 cores @ 3.0GHz
- RAM: 8GB
- Storage: 30GB SSD
- Bandwidth: 2-3 Mbps per player
Recommended Requirements
For medium servers (20-50 players) with moderate plugins:
- CPU: 8 cores @ 3.5GHz+
- RAM: 16-24GB
- Storage: 50GB SSD
- Bandwidth: 3-5 Mbps per player
High-End Requirements
For large servers (50-100+ players) with many plugins:
- CPU: 12-16+ cores @ 4.0GHz+
- RAM: 32-64GB
- Storage: 100GB+ NVMe SSD
- Bandwidth: 5+ Mbps per player
Factors Affecting Performance
Player Count
Rust scales non-linearly with player count. Each player adds:
- Network synchronization overhead
- Entity processing (items, structures)
- AI calculations (animals, NPCs)
- Combat calculations
Plugin/Mod Load
Popular plugins and their impact:
- Admin Tools: Minimal impact
- Economy: Moderate CPU increase
- Teleportation: Network overhead
- Custom Kits: Low impact
World Size
Larger maps require more resources:
- Small (2000): Less demanding
- Medium (3000): Standard
- Large (4000+): High requirements
Storage Recommendations
SSD is mandatory for Rust servers. HDDs cause:
- Very slow server startup
- Severe lag spikes
- Inventory desync
- Poor player experience
Critical: Rust is CPU-intensive. High single-core clock speeds are more important than total core count. 4GHz+ is recommended for 50+ players.
Network Requirements
Minimum Upload: Players × 2 Mbps
Recommended Upload: Players × 4 Mbps
# Example for 50 players:
# Minimum: 100 Mbps upload
# Recommended: 200 Mbps upload
Tick Rate
Server tick rate affects performance and gameplay:
- 30: Default, good balance
- 60: Smooth gameplay, requires more CPU
- 120: High-end only, significant CPU usage
Memory Usage
RAM usage scales with:
- Player count (primary factor)
- Number of active bases
- Entity count (items, structures)
- Loaded plugins
Approximate RAM usage:
10 players: 6-8 GB
25 players: 10-12 GB
50 players: 16-20 GB
100 players: 32-48 GB
Optimization Tips
- Disable unnecessary plugins
- Reduce tick rate if CPU-limited
- Use smaller world size for fewer players
- Enable entity cleanup plugins
- Regular server restarts
