Introduction to Unturned Server Optimization

​

Hardware Considerations

​

Config File Optimization

​

Commands.dat Optimization

// Performance Settings
Log 3                  // Reduced logging (0-7, higher = more logs)
Framerate 30           // Server tick rate (30 is optimal for balance)
Timeout 120            // Time until inactive players are kicked
Tick_Delay 0.015       // Delay between ticks (lower = more CPU usage)
Max_Ping 1250          // Maximum allowed ping
Max_Packets_Per_Second 800  // Limit packets to prevent flooding

​

Config.json Optimization

+InternetServer/YourServerName -Port=27015 -Secure -Framerate=30 -Rolling=Minute -PVP -No-Streaming -NoWorkshopExplicitLoading

​

Key Parameter Explanations

​

Scheduled Tasks

// Add to your Gamepanel scheduler
// Clean server every 6 hours
0 */6 * * * say "Server restart in 10 minutes!"
10 */6 * * * save
10 */6 * * * shutdown 60

​

Map Selection

​

Workshop Mods Optimization

1. Limit total workshop items - Each mod increases memory usage and startup time
2. Avoid redundant mods - Multiple mods with similar functions waste resources
3. Choose optimized mods - Some mods are better coded than others
4. Update mods regularly - Outdated mods may have unpatched performance issues

​

Database Optimization

1. Use connection pooling to reduce database overhead
2. Index frequently queried fields for faster lookups
3. Schedule regular database maintenance to prevent bloat
4. Use SSD storage for database files

​

Zombie and Item Spawn Management

"Max_Items_Spawn": 96,
"Max_Barrel_Drops": 4,
"Max_Zombies_Spawned": 64,
"Max_Animals_Spawned": 16,
"Zombie_Spawn_Interval": 15,

​

Vehicle Optimization

1. Limit total vehicles - Set reasonable vehicle spawns in your map configuration
2. Clear unused vehicles regularly
3. Use the vehicle decay option to automatically remove abandoned vehicles:
   "Decay_Vehicles": true,
   "Decay_Time": 604800,
   
4. Use plugins to limit vehicle spawning or automatically despawn unused vehicles

​

Server Maintenance Routines

1. Scheduled restarts every 6-12 hours:
   // Add to your Gamepanel scheduler
   restart
   
2. Regular map resets (every 1-4 weeks depending on your server type)
3. Clear items periodically:
   // Console command
   clean
   
4. Implement automatic backup before maintenance tasks
5. Monitor resource usage to identify performance trends

​

BattlEye Configuration

RConPort 2310
RestrictRCon 0
MaxPing 1000
MinFrametime 0.030
MaxPacketsize 1024
MinPacketLoss 0.0
MaxPacketLoss 0.2
MinPktRate 80
MinPktRateOnJoin 20
PacketFlood 2000

​

Plugin and Rocket Optimization

1. Limit the number of plugins - Each plugin increases overhead
2. Choose lightweight alternatives where possible
3. Disable unnecessary plugin features in configuration files
4. Update all plugins to their latest versions
5. Monitor plugin performance using timing tools

​

Network Optimization

1. DDoS protection - Use our built-in firewall or a service like Cloudflare
2. Optimize packet handling:
   Max_Packets_Per_Second 800
   Max_Ping 1250
   
3. Configure connection timeouts:
   "Timeout_Queue": 60,
   "Timeout_Linking": 30
   

​

Advanced Performance Tuning

1. Linux kernel tuning (if using a Linux-based server):
   sudo sysctl -w net.ipv4.tcp_keepalive_time=60
   sudo sysctl -w net.ipv4.tcp_keepalive_intvl=10
   sudo sysctl -w net.ipv4.tcp_keepalive_probes=6
   sudo sysctl -w net.core.somaxconn=4096
   
2. Process priority adjustment:
   // In your Wasabi Hosting Gamepanel startup script
   nice -n -10 ./Unturned.x86_64
   
3. Memory allocation optimization in your Gamepanel startup:
   export MALLOC_ARENA_MAX=2
   

​

Troubleshooting Common Performance Issues

​

Monitoring Your Server

1. Wasabi Hosting’s Gamepanel Console - Check for error messages and warnings
2. Resource Usage Graphs in Gamepanel
3. Server logs in /Servers/YourServerName/Logs/
4. In-game commands:
   /info     // Shows server stats
   /ping     // Shows connection quality
   /tps      // Shows current TPS (if using TPS monitor plugin)
