I dont even care about the performance. I just want some way to version my messages that is backward and forwards compatible and can be delivered in all the languages we use in production. I have tried to consume json over websockets before and its always a hassle with the evolution of the data format. Just version it in protobuf and push the bytes over websocket if you have a choice. Also, load balancing web socket services can be a bitch. Just rolling out our web socket service would disconnect 500k clients in 60 seconds if we didnt make huge amounts of work.
