Web2 days ago · The ProcessPoolExecutor class is an Executor subclass that uses a pool of processes to execute calls asynchronously. ProcessPoolExecutor uses the multiprocessing module, which allows it to side-step the Global Interpreter Lock but also means that only picklable objects can be executed and returned. WebJul 5, 2024 · asyncio is faster than the other methods, because threading makes use of OS (Operating System) threads. So the threads are managed by the OS, where thread switching is preempted by the OS. asyncio uses coroutines, which are defined by the Python interpreter. With coroutines, the program decides when to switch tasks in an optimal way.
