Joomla - How to speed up site
If you don't use extensions that require mootools.js then deactivate mootools.js. In the index.php at top insert this code:
<?php
$headerstuff=$this->getHeadData();
reset($headerstuff['scripts']);
foreach($headerstuff['scripts'] as $key=>$value){
unset($headerstuff['scripts'][$key]);
}
$this->setHeadData($headerstuff);
?>
