# How to Monitor Server FPS in Arma 3

> Track simulation FPS on your Arma 3 server to identify bottlenecks, diagnose AI desync, and use diagnostic commands for performance tuning.

## Performance Metrics: Server FPS

In Arma 3, "Server FPS" is not a measure of graphical smoothness, but rather a metric of **simulation cycles** per second. It dictates how frequently the server calculates AI pathfinding, projectile trajectories, and network synchronization. A low Server FPS results in "desync," causing vehicles to teleport, bullets to fail to register, and AI units to become unresponsive.

## Diagnostic Commands

You can monitor the health of your FREAKHOSTING server directly from within the game client.

<Steps>
  <Step title="Authenticate as Admin">
    Open the in-game chat and type:

    ```bash theme={null}
    #login YourAdminPassword
    ```
  </Step>

  <Step title="Initialize Monitor">
    Type the following command to begin tracking performance at a set interval:

    ```bash theme={null}
    #monitor 10
    ```

    *(The number represents the update interval in seconds).*
  </Step>

  <Step title="Analyze the Output">
    The server will print a status line to your chat console:
    `FPS: 48   Mem: 2048   Player: 15`
  </Step>
</Steps>

## Interpreting Server Health

Use the table below to determine if your mission is running optimally or if the server is overloaded.

| FPS Value     | Status         | Experience                                                                |
| :------------ | :------------- | :------------------------------------------------------------------------ |
| **50 FPS**    | **Perfect**    | The engine is running at its hard-coded cap. Minimal network lag.         |
| **30-45 FPS** | **Standard**   | Typical performance for a server with 40+ players and moderate AI counts. |
| **15-20 FPS** | **Struggling** | AI units will become slow to react. Driving may feel jerky or "laggy."    |
| **\< 10 FPS** | **Critical**   | The simulation is failing. Expect mass "desync" and disconnects.          |

<AccordionGroup>
  <Accordion title="Identifying Common Bottlenecks">
    * **Excessive AI Counts:** Having 500+ AI units active simultaneously will overwhelm even the fastest CPUs.
    * **Script Loops:** Check your server `.RPT` logs for recurring error messages. Infinite loops or heavy scripts running `onEachFrame` are common culprits.
    * **Garbage Collection:** Ensure your mission has a cleanup script to delete dead bodies, dropped weapons, and wrecked vehicles.
