[Nick Belaevski (JIRA)]

    [ https://jira.jboss.org/jira/browse/RF-1941?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12430525#action_12430525 ] 

Nick Belaevski commented on RF-1941:
------------------------------------

A little experiment.

Preparation:

1. YSlow installed to FF3
2. Tomcat configured to GZip CSS/JS files
3. common.css and all static images removed from demo site (that is because YSlow complains it cannot find expires header for them and we cannot do anything with that - there's ETag on all of them and caching occurs)
4. Default expire set to 2d+
5. Local address added to CDN list
6. Tree demo page opened

See results on screenshot attached: points 5 and 6 are "A" - high mark

> 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.
