Python thread pool and its principles and uses

In object-oriented programming, creating and destroying objects is very time-consuming, because creating an object requires obtaining memory resources or other resources. This is especially true in Java, where the virtual machine will try to track every object so that it can be garbage collected after the object is destroyed. Therefore, one way to improve the efficiency of service programs is to reduce the number of object creation and destruction as much as possible, especially the creation and destruction of some resource-intensive objects.

Python thread pool and its principles and uses

The cost of the system starting a new thread is relatively high because it involves interaction with the operating system. In this case, using a thread pool can greatly improve performance, especially when the program needs to create a large number of threads with short lifetimes, you should consider using the thread pool. The thread pool creates a large number of idle threads when the system starts. As long as the program submits a function to the thread pool, the thread pool will start an idle thread to execute it. When the function is executed, the thread will not die, but will return to the thread pool again and become idle waiting to execute the next function.
