Introduction to Unturned Server Optimization

Optimizing your Unturned server is crucial for providing a smooth gameplay experience for your players. This guide covers various techniques to improve your server’s performance on Wasabi Hosting’s Gamepanel platform.

​
Hardware Considerations

Unturned is CPU intensive, especially when handling vehicle physics and large numbers of zombies. Prioritize CPU performance over RAM in most cases. Wasabi Hosting offers optimized plans specifically designed for Unturned servers.

​
Config File Optimization

Unturned servers have several configuration files that can be tuned for better performance.

​
Commands.dat Optimization

The Commands.dat file in your /Servers/YourServerName/ directory contains essential startup commands. Here are recommended values for better performance:

// 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

Setting the Framerate higher than 30 significantly increases CPU usage with minimal gameplay benefits.

​
Server Configuration

Edit your server’s Config.json file (/Servers/YourServerName/Server/Config.json) with these optimized settings:

{
  "Browser": {
    "Broadcast": true,
    "Password": false,
    "Port": 27015
  },
  "Gameplay": {
    "Allow_Shoulder_Camera": true,
    "Anti_Cheat": {
      "Allow_Battleye_Client": true,
      "Kicks_Per_Minute_Threshold": 10,
      "Max_Flagged_Packets_Before_Kick": 30,
      "Max_Invalid_Character_Packets_Before_Kick": 20,
      "Max_Invalid_Vehicle_Packets_Before_Kick": 10,
      "Max_Ping": 1250,
      "Max_Successful_Teleports_Before_Kick": 5,
      "Max_Unsuccessful_Teleports_Before_Kick": 5,
      "Max_Vehicle_Distance_Before_Kick": 60,
      "Max_Walk_Speed": 15
    },
    "Assault_Rifle_Burst_Shots_Per_Second": 7.5,
    "Auto_Save_Interval_Seconds": 900,
    "Allow_Workshop_Items": true,
    "Bleeding_Damage": 5,
    "Broken_Legs_Damage": 10,
    "Bullets_Hurt_Barricades": true,
    "Bullets_Hurt_Plants": true,
    "Bypass_Buildable_Restrictions": false,
    "Decay_Time": 604800,
    "Decay_Vehicles": true,
    "Fall_Damage": true,
    "Food_Decrease_Multiplier": 1.0,
    "Gravity_Multiplier": 1.0,
    "Group_Limit": 0,
    "Hair_Grow_Time": 259200,
    "Item_Despawn_Seconds": 600,
    "Weapon_Jam_Quality_Threshold": 10,
    "Max_Items_Per_Container": 40,
    "Max_Items_Spawn": 128,
    "Max_Barrel_Drops": 5,
    "Max_Zombies_Spawned": 96,
    "Max_Animals_Spawned": 24,
    "Zombie_Spawn_Interval": 10,
    "Player_Height_Threshold": 12,
    "Player_Stance_Samples": 32,
    "Player_Sprinting_Grace": 0.75
  },
  "Login": {
    "Timeout_Queue": 60,
    "Timeout_Linking": 30,
    "Queue_Size": 10
  }
}

Adjust Max_Zombies_Spawned and Max_Animals_Spawned based on your server’s performance. Lower values improve performance but reduce game difficulty.

​
Config.json Optimization

Optimize your Unturned server startup parameters in the Gamepanel:

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

​
Key Parameter Explanations

ParameterDescriptionRecommended Value
-FramerateServer tick rate30 (optimal balance)
-RollingSave intervalMinute (prevents data loss)
-No-StreamingReduces map streaming overheadEnabled for better performance
-NoWorkshopExplicitLoadingMore efficient mod loadingEnabled for better startup times
-LogLevelDetail level of logging1 or 2 (higher values increase overhead)

Using -LogRcon can create large log files. You can schedule log cleanup tasks to prevent this.

​
Scheduled Tasks

Set up these 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

You can automate these maintenance tasks using the Gamepanel scheduler feature.

​
Map Selection

The map you choose significantly impacts server performance:

Large, detailed maps with many objects will significantly impact server performance, especially with higher player counts.

​
Workshop Mods Optimization

Mods can significantly impact server performance:

  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

If your server uses MySQL for plugins or economy:

  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

Adjust these settings in your Config.json file for better performance:

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

Reducing the number of simultaneously spawned zombies and items dramatically improves server performance, especially on large maps or with many players.

​
Vehicle Optimization

Vehicles are one of the most resource-intensive aspects of Unturned servers:

  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

Implement these maintenance routines for optimal performance:

  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

You can automate these maintenance tasks using the Gamepanel scheduler feature.

​
BattlEye Configuration

BattlEye anti-cheat can impact performance. Optimize its settings in BattlEye/Config/BEServer.cfg:

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

If using Rocket mod for plugins:

  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

Some popular Rocket plugins like Economy, Jobs, and extensive permission systems can significantly impact performance.

​
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

For experienced administrators on Wasabi Hosting servers:

  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

Monitor your server’s performance using:

  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)

By implementing these optimization techniques, you should see a significant improvement in your Unturned server’s performance on Wasabi Hosting. If you continue to experience issues, contact our support team for assistance.
