# How to Fix Icarus Server Lag and Performance Issues

Knowing how to fix Icarus server lag and performance issues can save your game when a server slows down. Lag usually comes from an overloaded CPU, large bases, or a weak connection, and the fix depends on whether the problem is the server or your own PC.

---

## Restart the Server

A server that has been running for a long time can slow down as it uses more memory.

* Access the [Apollo Panel](https://control.sparkedhost.us/).

* Click **Restart**.

* Once it starts, connect to the server and watch CPU and RAM usage in the panel.

If either one is constantly maxed out. Refer to these fixes:

## High CPU Usage

### Lower Max Players

* Access the [Apollo Panel](https://control.sparkedhost.us/).

* Stop the server.

* Go to the **Files** tab.

* Navigate to the following directory: \`Icarus/Saved/Config/\`

* Open the \`ServerSettings.ini\` file.

* Find and lower the \`MaxPlayers=\` line.

* Click **Save Content**.

### Game Workload

* Build smaller bases.

* Remove dropped items and deployables you don't use.

* Limit large farms and animal pens.

* Avoid running many crafting queues at once.

## High RAM Usage

### Schedule Restarts

* Access the [Apollo Panel](https://control.sparkedhost.us/).

* Navigate to the **Schedules** tab.

* Restart the server about once a day, so memory doesn't build up. Schedule restarts [here](https://help.sparkedhost.com/en/article/how-to-create-schedules-and-auto-backups-nynff5/).

### Remove Mods

* Access the [Apollo Panel](https://control.sparkedhost.us/).

* Stop the server.

* Go to the **Files** tab.

* Navigate to the following directory: \`Icarus/Content/Paks/mods\`

* Remove any mods you don't need.

* Start the server.

### Upgrade Your Plan

If the RAM is still maxed out after these steps, your plan may not have enough memory for the server. Upgrade your plan or [contact support](https://billing.sparkedhost.com/submitticket.php) if unsure.
