6 Best WordPress Caching Plugins for Speed and Performance

Best WordPress Caching Plugins

Do you want to speed up your website with a really good caching plugin?

Caching reduces the time it takes to load a page on your website. This results in a better user experience, lower bounce rates, and potentially higher search engine rankings.

In this guide, we reveal the top caching plugins available for WordPress websites.

1. WP Rocket

WP Rocket is a popular and powerful caching plugin for WordPress websites. It helps improve your PageSpeed performance score and optimize your Core Web Vitals. We’ve used this plugin on our own websites and it works wonders!

How it works is it creates and stores static copies (caches) of your web pages. When a visitor accesses your website, these stored pages are served quickly instead of generating the page content from scratch.

WP Rocket is known for its user-friendly interface, making it accessible to both beginners and experienced WordPress users. When you install the plugin on your site, it auto-applies 80% of website performance best practices.

This not only saves you time, but you don’t need to know any of the technical stuff to get your site running at faster speeds.

Here’s a look at the cache settings options in the dashboard:

Everything can be done with the click of a button. It’s a breeze as there’s no coding needed.

WP Rocket includes lazy loading functionality for images and videos. This means that images and videos are only loaded when they become visible on the user’s screen.

The plugin can optimize your WordPress database too by removing unnecessary data, spam comments, and revisions.

2. WP Super Cache

WP Super Cache is a popular and free caching plugin for WordPress websites. It’s created by Automattic, the same folks behind WordPress.com.

This plugin functions a bit differently than others. 99% of users will be served static html files. The same cached file can be served thousands of times over to 3 types of users:

  • Users who are not logged in
  • Users who have not left a comment on your blog
  • Users who have not viewed a password-protected post

If the user is logged in, or has left comments, then a custom cached file will be created that’s tailored to their visit. So those extra details will be displayed and cached for them.


  • Easy caching process
  • Built-in cache tester
  • Custom caching
  • Garbage collection of old and obsolete cached files
  • CDN integration

3. Sucuri Firewall

Sucuri Firewall is a powerful website security service that protects your WordPress site from online threats, including malware, hacking attempts, DDoS attacks, and more.

The Sucuri firewall acts as a Web Application Firewall (WAF) that sits between your website and incoming web traffic. It inspects incoming requests and filters out malicious or suspicious requests before they reach your website. This helps protect your site from known security threats and vulnerabilities.

With the Sucuri Firewall, you also get high-performance caching solution. You can cache your website content and enable gzip compression with a click of a button.

While not primarily a caching feature, Sucuri’s Firewall also offers a CDN to distribute your website’s static content to geographically dispersed servers. This can also help improve page load times by 60% on average and reduce server load.


  • Easy set up
  • Firewall with caching functionality
  • High-performance caching options
  • Multiple caching options
  • Reliable website uptime
  • Dedicated support

4. SG Optimizer

SG Optimizer is a WordPress plugin developed by SiteGround, a popular web hosting company. It is specifically designed to enhance the performance of WordPress websites no matter which web host you’re using.

That said, some of the features will work only if you’re using SiteGround’s hosting.

For all websites, the plugin offers advanced caching options, including dynamic and static caching. It generates static HTML versions of your web pages, reducing server load and improving page load times for visitors.

Next, it also uses browser caching, instructing web browsers to store static files locally. This reduces the need to re-download files on subsequent visits, further improving page load times.

The plugin includes features like minify HTML, CSS, and JavaScript files, which means it removes unnecessary spaces, comments, and line breaks from these files. Minification reduces file sizes and speeds up page rendering in web browsers.

Added to all this, SG Optimizer includes an image optimization feature that automatically compresses and resizes images to reduce their file sizes without sacrificing quality. Smaller images load faster and save bandwidth.

On the SiteGround environment, it offers Memcached caching which caches objects on your site. There’s also a built-in speed test to check your site loading speed.


  • Dynamic caching
  • File-Based caching
  • Browser-specific caching
  • Automatic purge
  • Image compression
  • Lazy load images
  • Database cleanup tool

Another feature that’s worth noting is that once your page or post is published, all cached files are deleted. The admin has the power to delete all cached files, minified CSS, and JS files manually.
