SocketJS: process all messages through one socket or open multiple?

Question

Socket.io

In general, you need a chat that is similar to LinkedIn. SocketJS has a multi-connect feature. But the question is - what is the advantage of this method and the disadvantages over a single-socket connection and message processing on the client? And how does this difference affect performance and load?

Thanks in advance

Answer 1

Chat makes no difference. It is better to drive all data through one socket. Memory will be used less, both on the server and on the client.
If you have a lot of traffic ala video, then it is better to use a separate socket for video-audio, or work via UDP. That. if there is a queue in one socket, then the second one will always be free + the signal traffic is not as big as audio-video.
In this case: chat is a signaling protocol and there is no point in bothering with additional sockets.
