In this case Ive found Flask-SocketIO, similar to Flask-Sockets but with a few key differences highlighted by the creator (Miguel Grinberg) here. how it would perform in real-life scenarios). For a worker based server you have to pick a fixed number of workers, and that gives you the maximum number of concurrent requests you can have.
