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.

Application-level memory control group memory reclamation

A memory swapping method and apparatus are provided. The method includes: selecting n to-be-swapped-out pages; compressing the n to-be-swapped-out pages into n compressed blocks, and buffering the n compressed blocks in a compressed data buffer area; organizing at least one of the n compressed blocks into m to-be-written units; and writing the m to-be-written units into a swap area of a non-volatile storage device in a maximum of m batches, where at least one of the m to-be-written units is stored in a segment of continuous space in the swap area. The method reduces a quantity of write times during memory swapping, thereby prolonging a service life of the non-volatile storage device.
