Abstract: An application-level memory control group of a first application may be created when the first application is opened. An anonymous page of the first application is added to a least recently used linked list of the application-level memory control group, and a file page of the first application is added to a global least recently used linked list. An application-level memory control group is created in a dimension of an application, and an anonymous page of the application is managed in a refined manner. In addition, a file page of the application-level memory control group may be managed based on a global least recently used linked list.

Abstract: Embodiments of this application provide a control method based on a vertical synchronization signal and an electronic device, to shorten a response delay of the electronic device and improve fluency of the electronic device without increasing load of the electronic device. The method may include: drawing, by an electronic device including a display screen, one or more layers in response to a first vertical synchronization signal; refreshing and displaying an image frame in response to a second vertical synchronization signal; adjusting the first vertical synchronization signal, so that the adjusted first vertical synchronization signal is delayed by first delay time relative to the second vertical synchronization signal; and drawing one or more layers in response to the adjusted first vertical synchronization signal.
