Caching in Joomla: An Essential Tool for Accelerating Your Website Speed


Hello Joomla enthusiasts! Today, we’re going to delve into the world of caching and its crucial role in Joomla. You might be wondering: What is caching and why is it so important? Let’s embark on this journey together!

Introduction to Joomla Cache

Caching, in the simplest terms, is a process that stores a version of your website content to deliver it quickly to the visitors without needing to generate it from scratch every time. The necessity of caching arises from its ability to significantly enhance website speed, thus, improving user experience and Joomla SEO ranking.

Joomla presents you with a variety of caching options: Page Caching, Conservative Caching, and Progressive Caching. Each type caters to different needs and situations, ensuring that your Joomla website functions optimally at all times.

Cache Settings in Joomla

To access the cache settings in Joomla, head over to System > Global Configuration > System Tab. In the Cache Section you will find 3 System Cache options:

  • Caching Disabled: As the name suggests, no caching happens when this option is selected.
  • Conservative Caching: This option caches the content for each visitor separately.
  • Progressive Caching: This more aggressive form of caching stores the same content for all visitors, making it especially beneficial for websites with mostly static content.

Cache Handler

Under the cache settings, there’s another crucial setting you need to know about – the Cache Handler. This option determines how Joomla stores the cached content. The two common cache systems are the ‘File’ and ‘Memcached’, each having their unique benefits.

Cache Time

The Cache Time is another significant factor that determines the lifespan of cached content. It’s essential to set the cache time based on the dynamics of your website. For instance, a news website may require a shorter cache time due to frequent content updates.

Page Cache

Enabling the page cache in Joomla is straightforward. Go to Extensions > Plugins, then search for “System – Page Cache” and enable it. It is a type of caching that saves an entire page’s HTML, significantly reducing server load.

Browser Caching

Browser caching takes caching a step further by storing static files (like CSS, JavaScript, and images) of your website in the visitors’ browsers. This reduces server load and increases the speed for returning visitors.

To enable it, simply navigate to

Extensions > Plugins, find “System – Page Cache”, and enable “Use Browser Caching”.

Joomla caching improves the website’s performance by storing a copy of your webpage after the first load. This cached version is then served to subsequent visitors, reducing the load on the server and providing a faster user experience. When a page is updated, the cache refreshes to reflect these changes. The check-in cache process ensures that the latest version of the page is always displayed to your visitors.

To disable caching in Joomla, follow these steps:

  1. Log in to the Joomla Administrator Panel.
  2. Navigate to ‘System’ -> ‘Global Configuration’.
  3. On the ‘System’ tab, find the ‘Cache Settings’ section.
  4. Set the ‘Cache’ option to ‘OFF – Caching Disabled’.

To clear the Joomla cache manually, you can do the following:

  1. Access your website’s file system either through FTP or your web host’s file manager.
  2. Go to the ‘cache’ folder, which is usually located in the root directory of your Joomla installation.
  3. Delete all the files and folders inside the ‘cache’ folder. Do not delete the ‘cache’ folder itself.

The cache time in Joomla refers to the duration for which the system stores the cached copy of your webpage. After this period, the cached version of the page will be discarded, and a fresh version will be created. The default cache time in Joomla is 15 minutes, but this can be adjusted to suit the dynamics of your website. You can find and adjust the cache time in the ‘System’ tab of the ‘Global Configuration’ settings.


Caching in Joomla is not just a feature but a necessity for every website aiming for top performance and superior user experience. Whether you’re using Page Caching, Conservative Caching, or Progressive Caching, remember that every type has its unique advantages that can be utilized based on your website’s needs.
