AJ Page Speed Insights Module

The AJ Page Speed Insights module uses Google’s PageSpeed API to analyze the content of your Joomla! site, then generates suggestions and illustrative graphics so you can optimize and make your site load faster.

The AJ Page Speed Insights module interacts with Google’s PageSpeed API which runs a number of diagnostic tests against a Joomla! web page, and analyzes the page's performance on a number of "rules" that are known to speed up page load time. The rules are based on general principles of web page performance, including resource caching, data upload and download size, and client-server round-trip times. They examine factors such as web server configuration, JavaScript and CSS code, image file properties, and so on. For each rule, PageSpeed gives a general score, using a simple red-yellow-green grading scheme, and suggests specific techniques for correctly implementing each rule. It also provides some automatic optimization of external resources included on a page, such as minifying JavaScript code and compressing images.
