13 Best WordPress Cache Plugins to Boost Site Speed

What is Caching and Why is it Important for Your WordPress Site?

If you’re running a WordPress site, it’s important to understand what caching is and how it can help improve your site’s performance.

Caching is a way of storing data in a temporary memory location so that it can be accessed more quickly.

When a user requests a page from your WordPress site, the server has to process a number of tasks before it can deliver the page. These tasks can include retrieving data from a database, running PHP scripts, and generating HTML output.

WordPress caching plugin can help speed up this process by storing the data in a temporary memory location, so that it can be accessed more quickly.

Just keep in mind when you make changes to your website, sometimes those changes don’t show up right away. That’s because your browser is loading a cached version of your website, which is a saved version or cached files of the last time you loaded that page. 

Clearing your cache forces your browser to load the most recent version of your website and the plugin responsible will start to cache file again.

Object Caching

Object caching, for example, stores data such as database queries in memory so that they can be quickly accessed the next time they are needed. This can dramatically improve performance, especially on sites with high traffic.

There are two main object caching systems that can be used with WordPress: Redis and Memcache. Both of these systems are fast and reliable, but they have different strengths and weaknesses.

Redis Object Cache

Redis 1024x419

Redis is an open source, in-memory data store that can be used as a database, cache, or message broker. It is often used to improve the performance of WordPress websites.

Memcache Object Cache

Memcached

Memcache is a open source, high-performance, distributed memory object caching system. It is often used to speed up dynamic websites by caching database queries and PHP code.

Both Redis and Memcache can dramatically improve the performance of WordPress websites. However, they have different strengths and weaknesses. Redis is better suited for sites with high traffic and complex data structures, while Memcache is better suited for smaller sites with simple data structures.

Page Caching

Another type of caching is page caching, which stores a static copy of a page so that it can be served up more quickly the next time it is accessed. This is especially helpful for pages that don’t change often, such as your home page or an About page.

There are a number of different caching plugins available for WordPress, and they all work in slightly different ways. However, they all aim to improve the performance of your WordPress site by caching data in a temporary memory location.
