Uvicorn
Uvicorn is a lightning-fast "ASGI" server.
It runs asynchronous Python web code in a single process.
Gunicorn
You can use Gunicorn to manage Uvicorn and run multiple of these concurrent processes.
That way, you get the best of concurrency and parallelism.
Uvicorn是單進程的ASGI server,
而Gunicorn是可以管理運行多個Uvicorn,也以達到並發與並行的最好效果。
