Hi Robert, I've read on Jean-Francis' blog that his new project Atmosphere https://atmosphere.dev.java.net/ would work on App Engine. Also the Servlet 3.0 spec has asynchronous comet built in. Not sure if thats an option with AE yet.
I wonder why XMPP lags? I have noticed this on EVERY XMPP app and code example that I have seen to date. Thats why I specifically asked about performance :). I just wonder if it's the protocol's much redundant overhead data being gziped causing decompression woes (the bends) on both ends? or perhaps the libraries. Though there are many of them and I doubt all back up under load. Have you noticed CPU spikes correlated with traffic at a disproportionate ratio? -- Thanks for the response.
