# Improve DayZ Server Performance

Improve Dayz performance: reduce lag, boost tick rate – optimization tips from NexoraHost.

**Quick answer:** Improve server performance with targeted config changes – check RAM/CPU usage, tune settings and remove heavy mods/scripts.

  A well-optimized DayZ server ensures smoother gameplay, fewer crashes, and a better overall experience for players.
  In this guide, you will learn how to improve the performance of your DayZ server at NexoraHost.

## Basic Performance Tips

  - Keep your server software always up to date
- Remove unused or broken mods
- Restart the server regularly (recommended every 4–6 hours)
- Use only optimized and trusted mods

## Optimize Server Settings

### 1. Adjust Player Slots

  Do not set the player limit too high for your hardware. A higher player count requires more CPU and RAM.

`maxPlayers = 40;`

  Tip: Start lower and increase gradually based on performance.

### 2. Clean Up Server Files

  Regularly remove unnecessary files such as:

  - Old logs
- Unused mod data
- Temporary files in /profiles

## Mod Optimization

### 1. Use Only Necessary Mods

  Each mod adds server load. Too many mods can significantly reduce performance.

### 2. Avoid Heavy Scripts

  Some mods use complex scripts that increase CPU usage. Replace them with optimized alternatives when possible.

### 3. Load Order Optimization

`-mod=@CF;@CoreMod;@BuilderItems`

  Keep dependencies first (e.g. Community Framework).

## Server Hardware Considerations

  - High single-core CPU performance is important
- At least 6–8 GB RAM for small servers
- NVMe SSD recommended for fast loading times

## Network Optimization

### 1. Correct Port Setup

  Ensure all required ports are open and not blocked by a firewall.

### 2. Stable Connection

  A stable network connection reduces lag and desync issues.

## Server Configuration Tweaks

### 1. Reduce AI / Dynamic Events

  Too many dynamic events or AI spawns can impact performance.

### 2. Adjust Object Persistence

  Too many persistent objects can slow down server restarts and runtime performance.

## Logging Optimization

  Excessive logging can cause unnecessary disk usage and performance drops.

  - Disable debug logging if not needed
- Rotate logs regularly
- Monitor log size growth

## Monitoring Performance

  Always monitor your server to detect bottlenecks early.

  - Check CPU usage regularly
- Monitor RAM consumption
- Watch for script-heavy mods

## Common Performance Issues

### Lag spikes

  - Too many active scripts
- High player count
- Unoptimized mods

### Long restart times

  - Too many persistent objects
- Large map modifications
- Heavy mod loading

### Desync issues

  - Network instability
- Server overload
- Incorrect tick rate behavior from mods

## Best Practices Summary

  - Keep mods minimal and optimized
- Restart regularly
- Use SSD/NVMe storage
- Monitor server performance continuously
- Scale hardware with player count
