html5 - Google Web Engine Api Channel vs Node.js+Socket.io -

-

please, me choose 1 use university project (i want develop shared multiuser whiteboard).

in particular, interested in performance of message exchange between users , server using channel api , socket.io: 1 quicker , why?

i have implemented initial version of whiteboard http://jvyrushelloworld.appspot.com/ following tutorial: http://blog.greweb.fr/2012/03/30-minutes-to-make-a-multi-user-real-time-paint-with-play-2-framework-canvas-and-websocket/ code used pretty same, except side , message exchange method: used python, google channel api message exchange; guy wrote tutorial used play 2 framework , web sockets.

as see, web socket tutorial version works faster (don't know if mistake or google api channel performance issue). of course, lot of optimization can done improve performance, wonder if worth go on using channel api project or better switch socket.io?
