Problems solved by technology

From the beginning of pre-reading to the maximum pre-reading value set by the system, it often takes several pre-reading processes, which reduces the response speed of data usage, resulting in a slightly longer waiting time, which in turn causes the system to reflect phenomena such as freezes

Abstract

The invention discloses a data pre-reading method, a mobile terminal and a computer readable storage medium. The method comprises the steps of obtaining a pre-reading request of target data; acquiringmemory information and IO information according to the pre-reading request; when the memory information and the IO information meet preset requirements, adjusting the current pre-reading step lengthto be the maximum pre-reading step length supported by the system; and pre-reading the target data into the memory according to the maximum pre-reading step length. By means of the mode, the responsespeed of data use can be increased in a scene with sufficient system resources.

Description

technical field [0001] The present application relates to the field of caching, in particular to a data pre-reading method, a mobile terminal and a computer-readable storage medium. Background technique [0002] Usually, most disk I / O reads and writes are sequential, and ordinary files are stored on the disk in consecutive sectors. When reading and writing files in this way, the number of head movements can be reduced and the read and write performance can be improved. When a program reads a file, it usually accesses it sequentially from the first byte to the last. Therefore, multiple adjacent sectors on the disk in the same file are usually accessed by the reading process, and the read-ahead mechanism comes into being to improve disk performance and thus system throughput. [0003] Read ahead is to read multiple consecutive file pages from ordinary files or block device files into memory before the data is actually accessed. The read-ahead algorithm predicts the pages to...
