Abstract

The invention discloses a file pre-reading method and device based on a user space file system FUSE and electronic equipment. The FUSE at least comprises a kernel mode and a user mode; a user mode file system is pre-mounted on the user mode, a target cache region is preset on the user mode, and the file pre-reading method comprises the following steps: receiving a file reading request; in responseto the file reading request, reading a first sub-file in the target file from the user mode file system; calculating pre-read file information of other pre-read sub-files after the first sub-file according to the file information and the pre-read parameters of the first sub-file; and caching other pre-read sub-files to the target cache region based on the pre-read file information. According to the invention, the technical problems of relatively small kernel page setting and incapability of finishing large file pre-reading work due to adoption of a VFS layer pre-reading mechanism in a user space file system in related technologies are solved.

Description

technical field [0001] The present invention relates to the technical field of file processing, in particular to a file pre-reading method and device based on user space file system FUSE, and electronic equipment. Background technique [0002] In related technologies, implementing a file system in user space can greatly improve productivity, simplify the workload of providing a new file system for an operating system, and is especially suitable for various virtual file systems and network file systems. Network-based user file systems are often bottlenecked in performance because data is transferred across the network. For example, to read a large file, if every read request reaches the user state through the kernel state, and then transmits it through the network, then each IO will cost a lot, which will inevitably lead to poor application performance. In order to solve this problem, the currently adopted solution borrows the general read-ahead mechanism of the kernel VFS l...
