## Additional Requirements

For the Dashboard server:

* **Connection limit**: Increase the open file limit of the operating system if limited by host
* **Request handling**: Disable aborting request processing if users close the site (`ignore_user_abort` in php.ini)
* **PHP functions**: Ensure all [required PHP functions](/advanced/miscellaneous/required-php-functions-for-mainwp) are enabled

***

## Scaling for Network Size

As you add more child sites, your Dashboard server needs additional resources.

| Network Size   | Hosting Type     | Recommendations                                                                       |
| -------------- | ---------------- | ------------------------------------------------------------------------------------- |
| Up to 30 sites | Shared hosting   | Standard shared plans work well                                                       |
| 31-100 sites   | Reseller hosting | Additional server memory; enable **Optimize data loading** in MainWP Settings         |
| 100+ sites     | VPS              | At least 512MB PHP and WP memory; enable **Optimize data loading** in MainWP Settings |

<Note>
  The **Optimize data loading** setting adjusts how MainWP loads data to reduce memory usage. Find it in **MainWP > Settings > Advanced Settings**.
</Note>

## Checking Your Configuration

You can verify your server meets requirements from within MainWP:

1. Go to **MainWP > Info > Server**
2. Review the displayed PHP and server settings
3. Check for any warnings or recommendations

***

## Self-Check Checklist

* [ ] PHP version 8.1 or higher
* [ ] PHP memory limit at least 256MB
* [ ] cURL enabled with adequate timeout
* [ ] Required PHP functions available
* [ ] Server resources appropriate for network size
