Travel Time AJAX v. Web sockets

I would like to ask whether one should expect some different round-trip time (sending some information to the server and receiving a response) when implemented with web sockets (message) compared to standard HTTP GET. I assume that the web socket is already connected and DNS is resolved.

As I understand it, it would be different if the GET consisted of several hits in the underlying protocol, which I'm not sure about. Otherwise, I would expect the same results.
