Socket.io Performance optimisation 15'000 users-CodePudding

The

CodePudding user response：

You can load balance sokets.io servers.

I haven't do this yet, but you have informations about doing this here: https://socket.io/docs/v4/using-multiple-nodes

If you use node.js as http server : https://socket.io/docs/v4/using-multiple-nodes#using-nodejs-cluster

Alternatively, you can consider using redis for that. There is a package that allow to distribute trafic on a cluster of process or server:

CodePudding user response：

You do not have to manage load balance if you have up to 15k to 20k Users, follow the below instructions.

In socket code do not use await async.

In socket code do not use any DB query.

Use a socket to take data from someone and provide those data to others, if you want to store those data do it using APIs before or after you send it to the socket.

It's all about how you use it. queries and await all this will slow your response and load, there is always a way to do things differently.

The above 3 suggestions boost my socket performance, I hope it does the same for you.
