Problems solved by technology

However, since the number of pending tasks in the task queue is variable, the maximum number of concurrent threads is fixed, which may lead to too many pending tasks in the task queue, and the pending tasks cannot be executed in time

Abstract

The application discloses a method and a device for controlling thread quantity in a thread pool. An embodiment of the method includes steps of acquiring quantity of tasks to be treated in a task queue of the thread pool; increasing the maximum concurrent thread number of the thread pool according to a predetermined rule since the quantity in responding to the to-be-treated task is more than the first predetermined quantity, and the CPU use rate of the system where the thread pool locates is less than the predetermined threshold value; establishing a thread according to the increased maximum concurrent thread number. By the method, the running efficiency of the thread pool is improved.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a method and device for controlling the number of threads in a thread pool. Background technique [0002] In a multi-process / multi-threaded operating system, time-consuming operations are usually handled by a separate thread. On the one hand, it is to avoid blocking the main thread and not affect the normal interactive operation of the user. On the other hand, it is to improve CPU performance. Utilization, improve the speed of task execution. However, if there are multiple time-consuming tasks that need to be processed and multiple threads are created at the same time, the CPU usage of the system will be high, which will cause each thread to process very slowly. In addition, it may also cause power consumption of the device / system Therefore, it is necessary to create a thread pool (ThreadPool) to control these threads, that is, to control the number of created thread...
