Written by | Tuesday, 01 March 2011 00:00 | Published in 2011 March
As you all know – Joomla!'s page loading speed is not one of the main advantages of the system. Of course, there is some advice you could follow and there are two very important things that needs to be done:
Increase your site's speed dramatically http://www.psdgraphics.com
  1. First thing is system plugins order, which should keep following order:
    • "System - cache" plugin should be last one in the list
    • all SEF plugins must be loaded right before cache plugins
  2. Create new .htaccess file or edit the one you have in your JOOMLA ROOT folder and paste this:
### @version $Id: htaccess.txt 10492 2008-07-02 06:38:28Z ircmaxell $
