Note that there is already many suggestions in http://jira.xwiki.org/jira/browse/XWIKI-2022, you should look at it and add yours.

Hello, This is a topic which I have been most interested in, as you will see from my screenshot in http://jira.xwiki.org/jira/browse/XWIKI-2022 loading of javascript is the biggest waste of time. I would like to develop some code to store scripts in a cache and concatenate commonly used scripts together and serve in a single request. I have tested this and it works very well, but I have to make the code neat enough for production. Something which will probably wait until we have our first foot of snow here because there is lots to do in the fall. also see: http://jira.xwiki.org/jira/browse/XSKINX-30 Concatinate always used scripts together and serve in single file. and http://jira.xwiki.org/jira/browse/XSKINX-9 Introduce some internal caching mechanism, since minimizing the file is resource intensive Caleb James DeLisle Thomas Mortagne wrote:

One of the things that would also help giving a much higher perceived performance, is reducing the JS and CSS of the Home Page. A lot of the JS and CSS that are loaded are NOT needed on the home page. With a loading of the global JS and CSS in 2 pages instead of one, the perceived performance of XWiki gets a huge boost I've done this with an #if in javascripts.vm and stylesheets.vm in some wikis and it was great.

Hi Thibaut, Some useful Web Performance resources: 1) Steve Souders, /High Performance Web Sites: Essential Knowledge for Front-End Engineers/: http://www.amazon.com/High-Performance-Web-Sites-Essential/dp/0596529309/re… Presentation of the 14 original rules upon which YSlow! was build on. Since then, a lot of new rules were added to YSlow! and Steve Souders moved from Yahoo! to Google and started working on Page Speed http://code.google.com/speed/page-speed/index.html 2) volume 2 /Even Faster Web Sites: Performance Best Practices for Web Developers/ by Steve Souders just came out: http://www.amazon.com/Even-Faster-Web-Sites-Performance/dp/0596522304/ref=s… Another 14 rules and tips which focus a mainly on Javascript optimization techniques. 3) http://www.stevesouders.com/blog/ Oana Thibaut Camberlin wrote:

According to a recent survey<

http://www.webdesignerwall.com/general/users-place-more-weight-on-design/

more than half people would drive away from a site with slow loading pages. There are several interesting issues that could be implemented to substantially improve page loading time in XWiki. Number one is aggreation of CSS and JS files in order to reduce HTTP requests. (For info, we have a total of 25 external CSS and JS files on a basic XWiki install when in the best world we would have just 2 - 1 CSS

and

1 JS) Someone interrested in working on this with me ?
