What do you mean by this? Async/await is coroutine-based internally.

What do you mean by this? Async/await is coroutine-based internally.

When a worker thread is scheduled to an I/O task, will the worker thread be park if the task is not completed? If so, when the worker threads are limited (for example, the machine is 1-core), it takes 1000 seconds to execute 1000 I/O tasks (assuming that each I/O task takes 1 second);

Under the same conditions, using goroutine takes only about 1.1 seconds.

Tokio is able to switch between multiple tasks on a single thread when they are waiting for IO. Check out this article.

When I want to write code to prove it, I have a problem. Can you offering some help ? #4442
