I plan to write a series, but I haven't thought about the directory yet. Let's take a look at this article today. I will organize it later.

There is a question: the performance of multiple threads in python is very slow due to the competition of GIL. However, the performance of multiple threads on a single cpu is not obvious, but the performance of the same code is particularly obvious after it reaches multi-core. So the reason why the performance of multiple threads in multiple cores is significantly reduced is the frequent cpu switching? The main problem should be: [will frequent switch
