Problems solved by technology

Since the minimum number of free bytes in a computer device is fixed, the determined memory recovery threshold is also fixed, so that the advantages of memory recovery technology cannot be fully utilized when performing memory recovery based on this memory recovery threshold

Embodiment Construction

[0034] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the following will further describe the embodiments of the present application in detail in conjunction with the accompanying drawings.

[0035] Before explaining the embodiment of the present application in detail, the application scenario of the embodiment of the present application will be described first.

[0036] At present, no matter how much memory is configured for the computer device, the operating system of the computer device may always run out of memory when it is running. When insufficient memory occurs, the operating system needs to take various measures to prevent the operating system from running abnormally. In a possible implementation manner, the operating system may reclaim a portion of memory currently in use to meet new memory requirements. In the Linux system, this method of reclaiming memory is also called "page reclaim (page re...

Abstract

The embodiment of the invention discloses a method for determining a memory recovery threshold value and related equipment, and belongs to the technical field of computers. The method comprises the step of adjusting a memory recovery threshold value based on a memory use parameter or a processor operation parameter in the computer equipment. Therefore, the embodiment of the invention provides a method for flexibly adjusting the memory recovery threshold value, so that the problem that the memory recovery threshold value is usually fixed in a memory recovery mechanism such as a ZRAM (Zero Random Access Memory) technology is avoided. Besides, the memory recovery threshold value can be flexibly adjusted, so that the problem that the advantages of a memory recovery technology cannot be fully played due to a relatively low memory recovery threshold value can be avoided, and the problem that the system performance is relatively low due to a relatively high memory recovery threshold value can also be avoided.

Description

technical field [0001] The embodiments of the present application relate to the field of computer technology, and in particular to a method and related equipment for determining a memory recovery threshold. Background technique [0002] In order to cope with insufficient memory in the computer device, a compressed partition is divided in the memory of the computer device. In this way, the original memory of the computer device includes the system partition and the compressed partition. The system partition is used to store the data originally placed in the memory, and the compressed partition is used to store the compressed data in the system partition. In addition, a memory recovery threshold is pre-configured, and the memory recovery threshold includes a low (low) threshold and a high (high) threshold. When the remaining capacity of the system partition is lower than the low threshold, some data is obtained from the system partition and compressed and placed in the compr...
