I’m looking into getting an openfire server started and setting up a strophe.js client to connect to it. My concern is that using http-bind might be costly in terms of performance versus making a straight on XMPP connection.
Can anyone tell me whether my concern is relevant or not? And if so, to what extend?
The alternative would be to use a flash proxy for all communication with OpenFire.
Thank you
BOSH is more verbose than normal XMPP, especially when idle. An idle BOSH connection might be about 2 HTTP requests per minute, while a normal connection can sit idle for hours or even days without sending a single packet (in theory, in practice you’ll have pings and keepalives to combat NATs and broken firewalls).
But, the only real way to know is to benchmark. Depending on your use case, and what your clients are (will be) doing, the difference might be negligible, or not.
