# DesiredWorkerCount

> The number of import worker processes the asset pipeline aims to maintain during an Asset Database refresh.

## Definition

* **Type:** Property
* **Namespace:** [UnityEditor](/engine/6000.3/script-reference/unityeditor.md)
* **Assembly:** UnityEditor

```csharp
public static int DesiredWorkerCount { get; set; }
```

### Remarks

The asset pipeline moves the number of running worker processes toward this value when possible, so the number of processes that actually run can be higher or lower. To make Unity start or shut down worker processes immediately, call [AssetDatabase.ForceToDesiredWorkerCount](/engine/6000.3/script-reference/unityeditor/assetdatabase/forcetodesiredworkercount.md).

Worker processes only import assets when the Asset Database refreshes out of process. For more information, refer to [AssetDatabase.ActiveRefreshImportMode](/engine/6000.3/script-reference/unityeditor/assetdatabase/activerefreshimportmode.md).

The default value comes from the [ **Desired Import Worker Count** setting](/engine/6000.3/manual/unity-editor/editor-settings-reference/comp-manager-group/class-editor-manager.md), which Unity calculates for a new project as a percentage of the logical CPU cores on the system. The `-desiredWorkerCount` command line argument overrides that setting.

Unity applies this property to the current session only and doesn't save the value.
