# Eco Server Lagging – Fix Performance & Reduce Lag

Eco dedicated server lagging? RAM, CPU, tick rate, world size & mods – step-by-step Eco server performance troubleshooting.

**Quick answer:** Fix Eco server lag by upgrading RAM (12 GB+), limiting world size, updating the server after patches and reducing concurrent players.

This guide shows you how to optimize your Eco server performance. Eco simulates a complex world with economy, ecology and dozens of players simultaneously – this can push even strong hardware to its limits. With these settings, your server will run more stable and faster.

## Eco's Special Feature: Everything Is Simulated

Unlike most games, Eco truly simulates everything – every animal, every plant, every tree, every water source and every weather event. On top of that, there's a complete economic simulation with supply and demand. This makes Eco unique, but also extremely resource-intensive.

## 1. Identifying the Biggest Performance Hogs

### Check Server Performance in Real Time

`# In the Server Manager:
# "Status" tab shows tick rate and player count

# Via console (Linux):
htop

# Important values:
# CPU: Consistently above 80% = action needed
# RAM: Above 80% = more RAM needed
# Load Average: Higher than CPU core count = server overloaded`

### Eco's Own Performance Statistics

`# In the Server Manager under "Graphs" tab:
# - Tick Time: Should stay below 50ms (20+ ticks/second)
# - Entity Count: Shows number of simulated objects
# - Active Threads: Shows running background processes`

## 2. Adjust World Size

World size is the biggest lever for performance. Every doubling of world size quadruples the area to be simulated:

    
        World Size
        Area (km²)
        Recommended Players
        RAM Requirement
    

    
        0.5 km²
        0.25
        1-3
        4-6 GB
    

    
        1 km²
        1
        3-8
        6-8 GB
    

    
        2 km²
        4
        8-20
        8-16 GB
    

    
        4 km²
        16
        20-50
        16-32 GB
    

For most servers, 1-2 km² is completely sufficient. Bigger isn't always better – a smaller world with higher density often plays more intensely.

## 3. Reduce Plant and Animal Spawns

Plants and animals make up a large part of the server load:

`# In the server configuration (Configs/Server.eco):
"PlantGrowthRate": 0.5,      // Default: 1.0 – halved = less CPU load
"AnimalSpawnLimit": 150,     // Default: 300 – reduces animal count
"TreeSpawnLimit": 5000,      // Default: 10000 – simulate fewer trees`

## 4. Optimize Economic Simulation

`# In the server configuration:
"EconomicSimulationInterval": 60,    // Default: 30 – update less frequently
"MaxStoreOffers": 100,               // Default: 200 – simulate fewer offers
"CurrencySimulationEnabled": true,   // Set to false if no currency is needed`

## 5. Restart Server Regularly

Eco often runs for weeks on a server. Over time, data accumulates and performance declines:

`# Set up daily restart (crontab)
0 4 * * * /path/to/eco-restart.sh

# restart.sh content:
#!/bin/bash
# Warning to players (5 minutes before)
echo "Server restart in 5 minutes!" | wall
sleep 300
# Cleanly shut down and restart server
systemctl restart eco-server`

## 6. Hardware Tips Specific to Eco

    - **CPU:** Eco benefits from multi-core CPUs – unlike most game servers. 6-8 cores are ideal
- **RAM:** Eco is extremely RAM-hungry. 16 GB minimum, 32 GB for worlds over 2 km²
- **Storage:** NVMe SSD is mandatory. The world is constantly loaded and saved
- **Single-Thread vs. Multi-Thread:** Eco uses multiple cores effectively. More cores = better, but high clock speed per core remains important

## 7. Check Mods for Performance Impact

    - Each mod increases server load. Only install what's really needed
- Large mods like Big Shovel or WorldEdit have little performance impact
- Mods that add new simulations (new animals, plants, weather systems) heavily strain the server
- Temporarily disable mods and compare server performance

## 8. Limit Player Count

Each additional player increases load disproportionately because they explore new areas and influence the economy:

`# In the server configuration:
"MaxPlayers": 20,              // Adjust to your hardware
"PrivateServer": true,         // Only invited players
"WhitelistEnabled": true       // Enable whitelist`

## 9. Storage Space Management

Eco worlds grow over time. Check storage regularly:

`# Check disk space
df -h

# Check storage folder size
du -sh ~/eco-server/Storage/

# Delete old backups
find ~/eco-backups/ -name "*.zip" -mtime +30 -delete`

## Quick Checklist

    - Adjust world size to player count (smaller is better than larger)
- Reduce plant and animal spawns
- Increase economic simulation interval
- Restart server daily
- Deactivate unnecessary mods
- Limit player count
- Provide sufficient RAM (16 GB minimum)
- Use NVMe SSD
