How to optimize Joomla for better performance?

Joomla script is not a 'heavy' application by default, however if it is not maintained properly, it can become slow and overload the server. Here are some basic tips on how to optimize your Joomla script: * Reduce the number of articles which appear on your front page. * Enable caching for your Joomla. * Disable/remove all components/modules/plugins you are not using. * Install an additional database optimization component such as this one http://www.sm2joomla.com/component/option,com_docman/task,cat_view/gid,79/Itemid,101/. * Enable debugging from the Joomla admin area > Global Configuration and check the number of queries executed. The higher the number, the slower your application will run. If the number of queries exceeds 70, you may consider disabling the extension which is making the most queries. * Check your website using this online tool http://www.websiteoptimization.com/services/analyze/. It will give you valuable information on what modifications can be made in order to improve its performance. * Decrease the number of external and internal links on your pages. Leave only the most important ones.
