Przemyslaw Jaskierski commented on RF-1941:
-------------------------------------------
Nick,
Thanks for looking at this. Your results are good because you have "ALL" load strategy for RF scripts and Style. Set it to default and try this on a page which contains a lot more than one RF component (AFAIR demo site very often has +-1 element per page, because it's demoing it's use, it's not a reliable test case - it's nothing compared to what you'd expect from a real-world application).
The "ALL" load strategies are not very suitable in real-world environment, because these loads +-200 kB to cold caches for a first-time visitor (and are added automatically to EVERY page, even if it doesn't have any RF component).

> 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.
