[google-appengine] Re: How quick is delivering a message through Channels API
According to this talk, the latency should be no worse than pulling at any frequency rate http://www.google.com/events/io/2010/sessions/building-real-time-apps-app-engine-feed-api.html In practice, we use channel API in project Yaac ( http://code.google.com/p/yaac/) to push back query results piece by piece and it works quite good, the latency is just neglectable -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.

Certainly faster than a second.

I've swiched from pulling to channel without problem. Like Max say, latency is neglectable. It also save bandwith and cpu time. Still a little billing issue: channel are cheap but free quota is only 100 opened chanels per days. In my case I'm going to pay the 9$ only for channels. -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.

Re: [google-appengine] Re: How quick is delivering a message through Channels API
My initial tests on Channels showed that a small latency exists, but it's only when establishing the connection. For instance, in the _ah/connected handler, if you send a message as soon as the connection opens, that message will be received with a latency of around 1 second. However, next messages are a lot quicker to be transmitted.
