+ Optional RAM is commonly used by an application to store data in a cache
+or keep data in a temporary buffer to improve the performance of the application.
+Optional RAM is allocated based on the priority assigned to the applications. Applications can request for optional RAM when additional RAM is required
+to improve the performance, but the application can still execute the tasks
+without the optional RAM allocation. The main purpose of optional RAM is: An application can safely allocate a large amount of optional RAM without
+the risk of affecting other applications. An application is able to release the optional RAM whenever it is needed
+for other applications without getting closed. As the application can still
+run without the optional RAM in limited performance mode.
+
In order to allow OOM Monitor to release optionally allocated RAM, an application
+must provide an OOM plug-in. For more information on OOM plug-ins, refer to
