WordPress pages are “dynamic”. This means that they are built on the fly every time someone visits a post or page on your site.
To build your pages, WordPress has to run a process to find the required information, put it all together, and then show it to your user.
This process involves a lot of steps, and what can really slow down your site when there are several people who visit at a time.
That’s why we recommend that each site using a WordPress cache plugin. Caching can make your WordPress site anywhere from 2x to 5x faster.
Is that how it works.
Instead of going through the entire process of generating the page every time the plug-in caching backs after the first load the page, and then serves the cached version for each subsequent user.
As can be seen in the charts above, when a user visits your WordPress site, the server retrieves information from a MySQL database and PHP files. Then he puts it all together in the HTML content that is served to the user.
It is a long process, but you can skip a lot of that when the storage cache is used instead.
There are a lot of good WordPress Cache plugins available, but the use of any of Rocket WP (premium) or WP Super Cache plug-in (free) is recommended.
Visit our step by step guide on how to install and configure WP Super Cache on your WordPress site. It is not difficult to set up, and visitors will notice the difference.
