Web Page Performance
Optimize the order of styles and scripts (15)
The following external CSS files were included after an external JavaScript file in the document head. To ensure CSS files are downloaded in parallel, always include external CSS before external JavaScript.
css.php
css
jquery.jgrowl.css
css.php
css.php
css.php
appbanner.css
css.php
css.php
css.php
5 inline script blocks were found in the head between an external CSS file and another resource. To allow parallel downloading, move the inline script before the external CSS file, or after the next resource.
Put CSS in the document head (2)
CSS in the document body adversely impacts rendering performance.
2 style block(s) in the forum.php body should be moved to the document head.

I'm not sure that this article works for 4.2.2....

It does. I have most of the recommendations implemented on my 4.2.2.

Just Step1, the .htaccess rules tweaks, will fix many of the problems you posted and thats a simple copy and paste and its up and running in less than a minute.

The rest take more time to implement.

Cheers, That was the first one I added. I'll work through the rest now.....Thanks!
