Here are the tips the help improve your Joomla site performance.
1. Enable Joomla cache
When a visitor loads a page in Joomla site, Joomla fetches content from database, loads extensions (modules, plugins, components) required in that page and template files, which then renders as a single page, thus the whole process takes time. Those things can be solved by Joomla caching system. Once the plugin is enabled, the first time someone loads a page, the result from the process above are stored and the visitors then get the stored version of that page instead of repeating the whole loading process.
There are 2 steps involved to enable Joomla cache.
1.1 Enable Cache setting in Global configuration
Please navigate to: “System → Global Configuration” then open the “System” tab where you can find the “Cache Settings”, select the Conservative caching or Progressive caching.

3. Keep your site clean
In your site, you can use many extension that handle different functionality but be aware of choosing extensions, some extensions, which are not optimized can slow down your site. Also, more extensions you choose to display in front-end, the more HTTP requests they will require to render. So keep your site as light as possible for better performance. Its a simple math, if its heavy it is bound to take time to load.
4. Optimize images
Images are a big part in a web site, nice image can improve content but it is also the main reason to make your site loading slow. Here are some tips you should take a look:
- Use image when you really need it
- Don’t use large image and don’t add too many images to a single page.
- Using tools like Adobe Photoshop to reduce image file size
5. Using CDN to load media
CDN stands for content delivery network, it is an interconnected system of cache servers that use geographical proximity as a criteria for delivering Web content. A content delivery network helps speed up your website a lot by shortening the distance between the person visiting your site and the server delivering the content.
CDN is especially well suited for delivering media such as: video, audio, images, etc. So instead of loading those media from server, it loads from CDN, it’s more efficient and reliable. There are many extensions that can help you with this such as JA S3 Amazon or other content networking extensions on JED.
JA Amazon S3 Component brings the power of cloud computing to Joomla Hybrid hosting is now possible, load site from your server and files: images, video, documents, etc from Amazon Content Delivery Network
6. Optimize CSS and JavaScript
When browser render content from a site it must process all the style and layout information for that page. As a result, the browser will block rendering until external stylesheets are downloaded and processed, which may require multiple round-trips and delay the time to first render. This can be resolved by compressing CSS and JavaScript.
CSS and JS optimization is the process of removing unnecessary or redundant code in CSS, JS files to reduce file size then joins CSS and JS files then number of requests will be decreased.
You can manually do it but it’s not recommended as it take time and it is quite risky. You can use framework that supports CSS and JavaScript optimization. T3 framework is a good choice you should try.
In the General setting of the framework, enable CSS and JS optimization, you can exclude files for optimization then save setting, that’s it.
