The invention provides a read-write bandwidth performance optimization method and system, and the method comprises the steps: distributing the corresponding Inode information in a file system API instance in a balanced manner when a directory or a file is created; and when the read-write request is processed, calling the file system API instance to perform read-write operation according to the corresponding Inode information when the directory or the file is created. According to the method, in the stage of creating the file or the directory, the file system API corresponding to the file or the directory is distributed in a balanced mode, unnecessary time consumption caused by accumulation of creation requests of the file and the directory is avoided, and the speed of requesting reading and writing is increased. According to the method, when read-write operation is carried out on a file and a plurality of lower-layer file system APIs are called, balanced distribution and autonomous switching of NFS read-write requests are carried out, and it is ensured that each file system API instance can process more requests as much as possible; and when the sizes of the files of the read-writerequest are not fixed or are greatly different, the files can be switched back and forth on each file system API instance, so that the API processing request is prevented from being unbalanced.
Description
technical field [0001] The invention relates to the technical field of read and write request processing, in particular to a method and system for optimizing read and write bandwidth performance. Background technique [0002] The NFS (Network File System, Network File System) server provides external services through the shared directory, and the client can mount it on the shared directory to access data on the server. For the client, the read and write bandwidth of file data is an important indicator to measure the performance of the server. In some business scenarios, such as satellite scenarios and high-performance computing scenarios, due to the large amount of data and frequent read and write operations, the read and write bandwidth of file data is a major bottleneck for this business, and the improvement of read and write bandwidth is imminent. [0003] After receiving the read and write request, the NFS server will check whether the cache information of the read and ...
