# Increasing Swap Space in FlyWP

Source: https://flywp.com/docs/server/server-architecture/increasing-swap-space-in-flywp/

### Overview

Swap space acts as overflow memory when your server’s RAM is fully utilized. While FlyWP allows you to adjust swap size, each server is already provisioned with an **optimized swap configuration by default**.

:::note
The value shown in the dashboard (e.g., 1 GB) is simply the selectable option, not necessarily the currently optimized setup applied to your server.

### Where to Find It

1. Go to **Server Dashboard**
2. Navigate to **Settings**
3. Locate the **Swap Space** section

### Default Behavior

- Every FlyWP server is configured with an **optimized swap size automatically**
- The dropdown displays preset values for manual adjustment
- You typically **do not need to change this setting**

### When (and When Not) to Increase Swap

**Avoid increasing swap unless necessary.** In most cases, the default optimized configuration is sufficient.

Only consider increasing swap if:

- Your server consistently runs out of memory
- You notice performance issues due to memory pressure
- You are running unusually memory-intensive workloads

### How to Increase Swap Space

If you’ve determined that increasing swap is necessary:

1. Open the **Swap Size** dropdown
2. Select your desired swap size:
   - 1 GB
   - 2 GB
   - 4 GB
   - 8 GB
   - 16 GB
3. Click **Update Swap**

### Important Notes

- Updating swap may **temporarily disable it during resizing**
- Your server will be restarted and the entire process can take upto 5-10 minutes
- This can impact performance if your server is under heavy load
- Swap is **slower than RAM**, so it should not be used as a primary solution for insufficient memory

### Recommendation

Stick with the default optimised configuration unless you have a clear reason to change it. If you frequently need more memory, consider upgrading your server’s RAM instead of relying on swap.
