# How to Fix Terraria Server Lag and Rubber-Banding Enemies

> Fix Terraria server lag: lower Enemy smoothing to stop enemies skipping, turn on Slow liquids, settle water and check Statistics in the FREAKHOSTING panel.

To fix Terraria server lag on FREAKHOSTING, open **Game settings** and expand **Performance and safety**. Set **Enemy smoothing** to a value such as 15 to stop enemies skipping around (lower numbers are smoother but use more bandwidth; 0 is off), and turn on **Slow liquids** if lots of water or lava is moving. Click **Review and save** and restart. Type `settle` in the **Console** to settle all water.

| Difficulty | Time | Works on | Panel pages |
| - | - | - | - |
| Beginner | 5 minutes | Every FREAKHOSTING Terraria server | **Game settings**, **Console**, **Statistics** |

## What kind of lag do you have?

| Symptom | Likely cause | Fix |
| - | - | - |
| Enemies jump or teleport | **Enemy smoothing** is off (0) | Set **Enemy smoothing** to 15 or lower |
| Lag around lakes, lava or after digging into liquid | Many liquids moving | Turn on **Slow liquids**, type `settle` |
| Everyone lags at once | The server is busy | Check **Statistics** |
| Only one player lags | That player's connection | Ask them to test another server or connection |

## How to set Enemy smoothing

**1. Open Game settings**

Open your server in the [Game Panel](https://games.freakhosting.com) and click **Game settings** under **GAME SETTINGS**.

**2. Expand Performance and safety**

Click **Performance and safety** to expand it before typing.

**3. Set a value**

**Enemy smoothing** "Reduces enemies skipping around, at the cost of more bandwidth." New servers start at 0 (off). Click **Default** to use 15, or type a value from 0 to 60. Lower numbers mean smoother enemies and more data.

**4. Save and restart**

Click **Review and save**, then **Save changes**, and restart. The **Public server** preset also turns on smoother enemies.

The value is stored on **Startup** as **NPCStream** and written to `npcstream` in `serverconfig.txt` at every start.

## How to reduce liquid lag

1. Turn on **Slow liquids** in **Performance and safety** ("Limits how many liquids move at the same time"). Liquids then take longer to settle.
2. Type `settle` in the [Console](https://help.freakhosting.com/portals/game-panel/how-to-use-the-server-console.md) to settle all water now.

## Check server load

Open [Statistics](https://help.freakhosting.com/portals/game-panel/how-to-view-server-statistics.md) while players are online. Our test server used about 0.6 GiB of memory after starting a small world. If memory or CPU is near your plan's limit during play, fewer players at once or a smaller world helps. Small worlds load and save faster than large ones.

## Settings that don't help on a hosted server

| Setting | Why to leave it |
| - | - |
| **Process priority** | "Has no real effect inside a hosted container" |
| **Automatic port forwarding (UPnP)** | "Not used on a hosted server" |

## Frequently asked questions

### What is the best Enemy smoothing value?

15 is the default the panel offers. Go lower if enemies still skip, higher if players have slow connections.

### Does a large world cause lag?

Large worlds need more memory and take longer to save and load. Size can't be changed later, so pick it before the first start.

### Why does lag spike every few minutes?

The server saves the world every 10 minutes. Short pauses at those times can be saves. See [autosave and backups](https://help.freakhosting.com/games/terraria/configuring-auto-backup-interval.md).
