Embodiment Construction

[0020] In order to make the technical solutions and advantages of the present application clearer, the exemplary embodiments of the present application will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all implementations. Exhaustive list of examples. And in the case of no conflict, the embodiments in this description and the features in the embodiments can be combined with each other.

[0021] The inventor noticed during the invention that:

[0022] Through the analysis of the samba software code, it is found that the main reason lies in the read and write thread model;

[0023] For write operations, multi-threaded writing to the same file introduces race conditions, resulting in a large number of thread switches, which not only increases latency, but also reduces CPU utilization;

[0024] For read operations, multiple threads reading ...

Abstract

The invention provides a file processing method and device. The file processing method comprises the steps of receiving an operation request sent from a client by a main thread, wherein the operation request comprises operated file IDs; carrying the operation request into the files based on the file IDs in the operation request by the main thread and storing the files in a to-be-processed file queue in sequence; and when files in the to-be-processed file queue need to be processed, obtaining the files from the to-be-processed file queue by a working thread and processing operation requests of the files one by one. As the main thread in the embodiment integrates the operation requests, and operation requests for the same file are integrated together, a race condition of writing operation is excluded through a processing serialization mode for the same files; as pre-reading and magnetic disk bandwidth can be fully utilized, no obvious negative influence to a universal scene can be generated, a performance demand on a high-concurrency and low-delay scene also can be satisfied, and operation requests in the high-concurrency scene can be balanced efficiently.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a file processing method and device. Background technique [0002] Network Attached Storage (NAS, NetworkAttachedStorage) technology is a mature, efficient, and low-cost storage technology that usually includes storage devices, system software, and file sharing services. Samba is an open source software that provides file sharing services based on the ServerMessageBlock (SMB) protocol. As a mature open source software, samba satisfies the needs of most application scenarios well. However, for some high-concurrency and low-latency scenarios, samba's performance is not satisfactory, often causing delays and low CPU utilization. and so on. [0003] The deficiencies in the prior art are: [0004] The existing samba software often has delays and low CPU utilization in some high-concurrency and low-latency scenarios. Contents of the invention [0005] The embodiment o...
