Charles has provided a good support for this demand.On the Charles menu, select "Proxy", "throttle Setting", in the dialog box that pops up, we can tick "Enable throttling" and set the type of

, Threadpoolexecutor will only take advantage of 4 threads. If the queue is full and a new task comes in, a new thread is started, and the task is not rejected because the queue is full, instead a new thread is started. The new thread runs the first task in the queue, freeing up space for the new task.The idea behind this algorithm is that the pool uses only the core threads (4) for most of the time, even if there is an appropriate amount of tasks waiting to run in the queue. The thread pool can
When you look at JS Advanced programming, you learn that a concept-function throttling-is designed to prevent the browser from crashing when certain events are triggered at high frequencies. Recently learned another concept, anti-shake, feeling and function throttling very much like, but also read a lot of blog posts, is understood.Difference:Function throttling: Frequent calls to a method that trigger at least one time within a certain intervalAnti-Shake: A method is called frequently within a
