Grzegorz Dubicki commented on RF-1941:
--------------------------------------

I would like to add one more suggestion:

* switching standard CSS images for components to utilize CSS Sprites technique,

In the mean time I have googled looking for some RF performance tips. I have found out that some of RF devs do not want to work on these kind of changes. Christian Bauer, for example, stated that "All in all, with todays client bandwidth, this is mostly irrelevant optimization." and that "The CSS sprite stuff is bullshit. Images are cached on the browser with no problem.".

Apparently Nick assigned to this issue thinks the same, because there is no trace on his activity on this issue here. :(


Excuse me, but first load 220.5K JS ((weight of compressed RF JSs)  + CSS + HTML + gfx > 300 kb website with > 30 HTTP requests  is noticably slowish even if you have a good broadband connection. And really fast broadbands are not common around the whole online world yet.

And I think I am not alone thinking that the first load time of a website is an important part of the overall impression and must be worked on and optimized.

- And what do all readers and voters think about it? Please comment on this issue and vote if you want it resolved! Let the devs know we are really interested in a better RF perfomance!

> 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.
