If you run a popular Joomla (or WordPress, Drupalor or any other PHP based CMS) website on either a dedicated server or VPS running WHM/cPanel, chance is you may have stumbled upon performance issues at some point.
Although improving Joomla's performance is a task that requires in-depth analysis, I thought I'd just write a couple of words on improving one aspect of your site's performance quickly and efficiently: PHP execution by using the APC or APCu opcode caching modules. Keep in mind that APC is compatible with PHP up to version 5.3.x. APCu replaces APC for PHP versions 5.4.x or newer and it's currently under active development.
Since PHP 5.3.x is considered obsolete, I'll cover the steps to have APCu installed on your server. If you run PHP 5.3.x either consider updating to 5.5.x/5.6.x or follow the steps below making sure you replace any "apcu" reference with just "apc" (minus the "u").

There have been endless discussions around how Joomla is developed and maintained. One thing is clear though: development is quite slow and new significant features for the end user have not yet been introduced since the Mambo days... It's one of the reasons we decided to build K2, so we could introduce more modern and popular features into Joomla now.
Here's an easy trick to replace the built-in Mootools library that comes in Joomla 1.5 with a compressed copy from Google AJAX Libraries API:
<!-- The following code goes into your template's index.php <head> tags, right before the <jdoc:include type="head" /> code block --><?php// Replace Mootools in Joomla with a compressed copy from Google AJAX Libraries API$document =&JFactory::getDocument();unset($document->_scripts[$this->baseurl . '/media/system/js/mootools.js']);?><script type="text/javascript" src="http://www.google.com/jsapi"></script><script type="text/javascript">google.load("mootools", "1.1.2");</script>There are 2 speed benefits by following this approach:
- We load a compressed copy of Mootools, so from around 73kb it drops to 18kb!
- We load Mootools from Google, thus our browser can simultaneously (in parallel) download Mootools along with the rest of our site's content.
It's a simple & easy trick we use on all our web projects, big or small. ;)
