Threading works really well with IO, but not CPU bound processes, hence why there's an asyncio lib for IO and a MP lib.Before Py3, you could only manually create threads using the threading lib and some people who don't like asyncio still prefer to use the manual threading lib, an external lib like trio, or … " - Io-bound processes are defined by

ThreadPool vs. Multiprocessing Pool in Python

WebA task that processes data from a disk, like counting the number of lines in a file is called an I/O bound. The I/O bound state is not considered desirable because it means that the CPU must stop running its operation while waiting for data to be loaded or unloaded from the storage. So, this makes I/O bound slower than non-I/O bounds.

Web21 aug. 2024 · For the IO-bound task, the bottleneck is not CPU. So the usual limitations due to GIL don’t apply here, and multiprocessing doesn’t have an advantage. Not only that, the light overhead of threads actually makes them faster than multiprocessing, and threading ends up outperforming multiprocessing consistently. Web11 jul. 2024 · What’s different to threading is that, asyncio is single-process and single-thread. There is an event loop in asyncio which routinely measure the progress of the tasks. If the event loop has measured any progress, it would schedule another task for execution, therefore, minimizing the time spent on waiting I/O.
