Server Configuration Tips
Performance

- Lower serverMaxViewDistance if experiencing lag (1600 default)
Security
- Always enable BattlEye for public servers
- Set a strong admin password (no spaces)
- Use RCON with password for remote management
- RCON whitelist limits which commands can be executed
