# Starts slowly after being idle

> It takes too long to start working with Design Editor.

## Application Pool Suspension

### Solution

To avoid the suspension of the Design Editor application pool, perform the following:

1.  Install the **Application Initialization** role. In Windows Server 2012 and higher, in the **Add Roles and Feature** Wizard, select the **Application Initialization** check box.

2.  In IIS Manager, right-click the Design Editor application pool, and then click **Advanced Settings**. Set the **Start Mode** option to `AlwaysRunning` and **Idle Time-out (minutes)** to `0`.

3.  On the left pane of IIS Manager, in the **Sites** list, navigate to your Design Editor application. Right-click the application node and select **Manage Application** > **Advanced Settings**. Set **Preload Enabled** to `True`.

4.  At the command prompt while running as an administrator, type `iisreset` to restart IIS.
