Latency should be generally significantly less than 500ms (that's not a guarantee, but it's what I've been seeing in my end-to-end tests).
Channel set-up time (the time between when you call goog.appengine.Channel.open and when your socket.onopen callback gets called) can be longer, sometimes up to 10 seconds or so. There are no reliability guarantees -- messages can be dropped or delivered out of order, but that should be the exceptional case rather than a normal case. If you have an application which _requires_ all messages to be delivered (eg. you're sending deltas to some complex data structure) you will need to add sequence numbers and checks yourself (though please feel free to file a feature request about this if you'd like). -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
