Whether events should be fired on a single worker thread, or many.
This property specifies whether the class should fire all events serially on a single worker thread, or concurrently on multiple worker threads. When this property is disabled (default), the MinWorkerThreadCount and MaxWorkerThreadCount configuration settings control how many worker threads are used to fire events.
Please refer to the Threading and Concurrency topic for more information.
Note: This property cannot be changed when Active is true, and cannot be changed within events.
