I have an application that has real-time notification functionality. To do this, I implement websockets together with Redis Pub/Sub. This is the current design:

So each user is subscribed to several redis channels (from the backend, then the backend sends this information to the frontend). Some channels have few posts and others more frequently, the issue is that since you are subscribed to many channels, there are times when, for example, 8-10 messages per second arrive at the backend. Should I have 2 websocket connections open (one for infrequent channels and others for those who publish more frequently) or is this loading not a problem and should I have one websocket per client?
