Abstract

The invention discloses a message queue based write and read method and system of a shared memory. The write method of the shared memory comprises the steps as follows: the message queue is adopted to execute the operation of multi-threaded in-queue push and single-threaded out-queue pop; and data of the single-threaded out-queue pop is written in the shared memory. With the adoption of the message queue based write and read method and system of the shared memory, the problem of blockage during communication between threads is solved, the resource consumption is reduced, system resources are sufficiently used, and the processing speed is increased, so that the throughput capacity of a server is improved.

Description

technical field [0001] The present application relates to the technical field of computer communication, in particular to a method for writing shared memory based on message queues, a method for reading shared memory based on message queues, a method for reading and writing shared memory based on message queues, and a method for reading and writing shared memory based on message queues. A shared memory writing system based on message queues, a shared memory reading system based on message queues, and a shared memory reading and writing system based on message queues. Background technique [0002] Throughput refers to the sum of the amount of data transmitted on the network during a performance test. For interactive applications, the throughput index reflects the pressure on the server. In the test of capacity planning, the throughput index shows the load capacity at the system level. With the continuous growth of user traffic and the continuous accumulation of enterprise da...
