Data block read-write performance optimization method and system, terminal and storage medium

The invention provides a data block read-write performance optimization method and system, a terminal and a storage medium, and the method comprises the steps: building a first core pool and a secondcore pool, and respectively distributing CPU cores for the first core pool and the second core pool; dividing the data block into a first grade and a second grade according to the size of the data block, and setting a first core pool to bind the first grade data block and a second core pool to bind the second grade data block; intercepting a read-write request, and obtaining a data block level ofthe read-write request according to the size of a data block of the read-write request; and allocating the read-write request to a core pool bound with the data block level, and processing the read-write request by a CPU core in the allocated core pool. According to the method, CPU core distribution is adjusted according to different data block flows in view of a user multi-data type scene, so that the front-end service ef
