10 Plugins to Help You Manage High Loads in Joomla

Last Updated: May 4, 2024By

High loads on a server are one thing web hosts detest. Failing to fix high-load issues can disrupt the smooth functionality of websites, and it sometimes makes it difficult to connect to databases resulting in errors. High loads can sometimes lead to outright downtime. Web hosts will frown at all these situations and could take strict penalties which could include an outright website suspension if the issue is not addressed.

Google confirmed that the speed factor will be more and more important for the ranking of a website. As if this wasn’t enough, Google Chrome is going to integrate a special badge to mark slow websites, as already happened with the passage to the HTTP protocol. This means that visitors will be scared of sites marked as slow and Google Chrome will suggest abandoning them. Consequently having a fast website is no more an option but a ‘must’!

In this post, we address the issues related to the Joomla website. We will note that generally, the same procedure applies to other website-building platforms. Here, our major concern is how to address the issue with performance plugins. We will conclude with a review of how you can generally address high-load issues in Joomla.


Installing Joomla plugins should be guided by the compatibility of the plugin with your Joomla version. Some plugins will break your site not because they are poorly coded but, in most cases, because the Joomla version is not compatible with the plugin. In that case, we recommend you upgrade your Joomla installation and retry to install the plugin again.

Now let us look at our top 10 recommended plugins to boost the performance of your Joomla website.

Page Cache Extended

Page Cache Extended generates copies of the rendered pages and loads the entire output on further requests from the previously generated cache files. By loading the content from static files, no database queries have to be processed. This improves the loading speed greatly!

Based on the core plugin “Page Cache”, this plugin’s functionalities have been extended with useful features. You can specify which pages should be cached with the help of an exclusion list for components and URLs. It is also possible to use the list like a white list to include the selected components or URLs.

The HTML code in the cached files can be minified to improve the loading speed even further. HTML comments (e.g. copyright references) can be kept in the optimized code. In addition, you can set a specific cache time independent of the global cache time which can be set in the Global Configuration.

PCE saves the complete HTML output additionally already compressed in the gzip format as a separate file. If the browser the visitor supports the gzip encoding, then the data can be returned immediately without the time-consuming compression process.

The plugin supports the clearing of the cache directly in the front end by a self-defined token. Individual pages can be specifically updated by entering the token in the URL. Thus, not all cached pages need to be purged completely.

Page Cache Extended, in combination with Device Specific Content (DSC), can create device-specific cache files (mobile, tablet, and desktop). For this, DSC simply has to be installed additionally. PCE automatically detects the installation and uses DSC to create device-specific static files.
