http://wiki.apache.org/myfaces/Performance is one of the most intresting ones. Well, most AJAX apps keep their state in client (but in quite different format than what's being done in JSF), but never submit everything at every request back to server. Apache's Trinidad (formerly Oracle ADF) has some kind of delta-protocol for client-server state synchronization. This adds complexity, but maybe it's wise on the performance side.
