[richfaces-issues] [JBoss JIRA] Commented: (RF-1941) Improve performance of RF-enabled pages using http://developer.yahoo.com/performance/rules.html

Marine Wacheux commented on RF-1941:
------------------------------------

After doing tests, I think generated javascript code (like "new PanelMenu(...)" ), and external JS files inclusion should be placed at the end of html body.
That way, html page can render progressively on browser, without having to wait complete files load. At the moment, all js files have to be loaded before page render, which can be long for users.

It is also important that this improvement is added in 3.1.x series, as I'm using JSF 1.1, and won't migrate to JSF 1.2 that is required by RichFaces 3.2

Thanks in advance.

> RF-1717 has been closed without addressing some great optimization opportunities described by Steve Saunders in his book. In short, these rules are here: http://developer.yahoo.com/performance/rules.html. Sticking to these rules _really_ helps.
> As Wim reported here: http://jira.jboss.org/jira/browse/RF-1717#action_12395166, the http://developer.yahoo.com/performance/rules.html#js_bottom helps a lot. It's a little bit confusing seeing this bug closed without addressing this (yes I know that this would require a general approach, that's why I report it here). Having a page rendering time of few seconds on a decent PC is not a good situation...
> I would strongly encourage to take stab at this, because there is a lot of other components that would benefit of this. This would make your product better.
