Abstract: This application provides a method and an apparatus, for accelerating cold startup of an application. The method includes after identifying an event that instructs an operating system of a terminal to cold start up an application, obtaining, from a plurality of dimensions, current status information related to the cold startup of the application, where the current status information includes a hardware configuration of the terminal, current load of the operating system of the terminal, resource overheads for cold starting up the application, and duration corresponding to each of a plurality of tasks in a process of cold starting up the application. The method also includes determining, by analyzing the current status information, a plurality of objects that need to be optimized in the current process of cold starting up the application; and then obtaining, based on the determined objects.

Abstract: A memory management method includes determining a memory page that needs to be swapped out of a memory, for each memory page that needs to be swapped out, generating, based on the memory page, a work task reclaiming the memory page, and allocating each work task to a dedicated worker thread for execution.

Abstract: A memory management method and apparatus to resolve a problem that a memory reclaiming rate is relatively low, severely affecting memory allocation performance in a scenario in which system memory is insufficient. The method includes determining a memory page that needs to be swapped out of a memory, for each memory page that needs to be swapped out, generating, based on the memory page, a work task reclaiming the memory page, and allocating each work task to a dedicated worker thread for execution. In this way, a plurality of central processing units (CPUs) process memory reclaiming in parallel, thereby accelerating memory reclaiming, and improving user experience.
