Abstract

The embodiment of the present application provides a page thrashing protection method and device for operating system memory reclamation, the method includes: the UE collects data from multiple application scenarios to obtain a thrashing page data set; the UE collects each element in the thrashing page data set The intersection set is obtained to obtain the page set list_thrashing_common where thrashing occurs in the multiple application scenarios; the combination of each element in the thrashing page data set is obtained to obtain the list_thrashing_all page set that has experienced thrashing; the UE combines the list_thrashing_common and the list_thrashing_all with A block is a basic unit for protection. The technical solution provided by this application has the advantage of high user experience.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a page thrashing protection method and device for operating system memory reclamation. Background technique [0002] The android system (linux kernel) adopts the principle of "usable and usable, reclaimed when busy" for memory. The recovery of memory caused some frequently used file pages to be scanned twice in a row, so that the activity quickly decreased to INACTIVE, and was finally recycled to the buddy system. Subsequent applications access the corresponding location of the file, so that the action of allocating physical pages / reading file content occurs again. Generally, this process is called page thrashing. [0003] Excessive page thrashing will lead to system performance degradation, affect user usage, and reduce user experience. Contents of the invention [0004] The embodiment of the present application discloses a page thrashing protection meth...
