I don't like the idea. At this point there is no reason to believe that
any browser with WebSockets implemented will break spec and need a
compatibility layer (the primary reason jQuery has ajax). I don't see
how jQuery could add any functionality to WebSockets, the api is already
quite nice, not to mention there are a large number of calls and parts
to the api, so there would be a pile of jQuery code just matching up the
api to make calls you could make without jQuery at all.
In any case, comparing WS to XHR in terms of speed is completely
pointless. XHR is a way to make a HTTP call from JS. WS is a
bi-directional non-HTTP socket which needs a dedicated server. They have
completely different purposes and use cases, speed is irrelevant to a
comparison. WS is simply "faster" because it doesn't need all the extra
cruft in a HTTP call and it's an open dedicated connection between the
browser and the server that doesn't close after every message.

The following Samples of text mining are speed comparison, WS vs XHR.
at my Office(same bloga.jp), the speed difference was following.
