SMB protocol write-in performance optimization method and device and readable storage medium

Abstract

The invention provides an SMB protocol write-in performance optimization method. The method comprises the following steps: receiving an SMB protocol writing request sent by a client; creating a storage buffer space in a cache sub-layer, receiving and analyzing to-be-written data, and storing the to-be-written data in the storage buffer space; calling a write-in interface, creating a buffer list inthe storage buffer space, and sending a write response to the client; and writing the to-be-written data into a compiling sub-layer, and destroying the buffer list. The invention further provides anSMB protocol write-in performance optimization device which executes the SMB protocol write-in performance optimization method. The memory copy logic in the write request process is optimized, meanwhile, and feedback is directly given to the client after the write interface is called, so that the write request response time is shortened, and the data write-in performance is improved.

Description

technical field [0001] The invention relates to the technical field of information processing, in particular to a method and program for optimizing writing performance of the SMB protocol. Background technique [0002] Samba is a software that implements the SMB protocol on Linux and UNIX systems. The program running on the server can respond to and process the SMB protocol requests sent by the client. The server can map local storage resources to the client through the samba software, and provide network storage services for the client. [0003] When the client makes a write request, it needs to establish a samba connection with the server. After the connection is established successfully, the server will generate a smbd sub-process, which will mount the back-end storage resources, create a lib instance, and follow up all SMBs of the client. All requests are processed by the smbd subprocess, and storage resources are accessed through the lib instance. The process of writi...

Problems solved by technology

In this process, there is a process of copying data from the data memory space to the buffer list memory space. When the amount of data to be written is large, writing failure or partial data loss is very likely to occur, and the writing process takes a long time. Long, which greatly affects data writing performance and efficiency
