Optimizing WordPress Performance: A Comprehensive Guide to Using WP Super Cache

WordPress is a popular content management system (CMS) for its user-friendly approach. Plugins and add-ons on WordPress are also easy to install and configure, which gives users a greater advantage in ranking highly on search engine results. Among several factors that ensure high ranking, speed is a key player. If your website doesn’t respond within a couple of seconds, the user is likely to shift to another website. So speed is an extremely important factor in ranking highly. And in optimizing speed, cache is a key factor in delivering content quickly to users. 

The effects of cache are invaluable for WordPress websites. The WordPress core comes with some object caching capabilities, but its functionalities are somewhat limited. Furthermore, the feature is also difficult to activate. Thankfully, WordPress developers have developed cache plugins that are much more user-friendly and optimize your site's performance significantly. WP Super Cache is among the most popular cache plugins on the market. We’ll discuss it comprehensively to help you optimize the speed of your website.  

What is WP Super Cache?

WP Super Cache

WP Super Cache is an open-source WordPress plugin as well as a cache plugin. The cache plugin stores copies of previously compiled HTML files to serve returning users. It’s a highly configurable plugin that also comes with separate cache delivery mechanisms and a multitude of other options and settings.

WP Super Cache supports Content Delivery Networks (CDNs). The plugin has automatic cache-clearing functionality that you can configure to delete unnecessary cached files. The preload mode is particularly useful because it helps make WordPress faster by caching your entire blog.

WP Super Cache boasts over 2 million active installations to date. This is a testament to how it impacts page loading times.

Why use WP Super Cache?

WP Super Cache can help your website rank highly in several ways. Some of the advantages are below:


Better SEO visibility: SEO ranking sees a boost with increased speed and reduced page load times. User retention also improves with reduced exit rates. Moreover, all the features of the cache plugin intend to optimize the overall performance of your WordPress website.


For performance optimization: WP Super Cache creates copies of your dynamic pages. With the WP plugin, users won’t have to wait for it; rather, they’ll be uploaded instantly, as requested. This will improve loading time, and visitors will experience faster results.

Good user experience: There’s a long list of improvements that users can experience with the cache plugin. However, proper planning and experimentation are required to correct things. This will take time and effort. Nevertheless, this is also possible with the installation of the WP Super Cache plugin. 


CDN integration: The CDN service fetches content quickly from the closest servers. This will also increase the speed of your website and the user experience on it.

Reduces the burden on servers: A caching plugin like WP Super Cache saves copies of the page and delivers them instantly to users without bothering servers. It will essentially save lots of resources by bringing the same results and instead serving the saved HTML copy. This also saves lots of time.

Go to Settings and find the Permalinks menu in the sidebar. Change the permalink settings, and then you can start the WP Super Cache plugin installation. Go to the plugin’s caching page and enable caching on your website.

WP Super Cache Work


WP Super Cache

WP Super Cache can serve in two separate ways:


Expert Mode: It uses Apache’s mod_rewrite module to serve users with static HTML files. Not a single line of PHP is executed with this method, which makes it the fastest and least resource-intensive way to serve cached content with WP Super Cache. However, this will require more configuration, which could be difficult for less experienced users. 


Simple Mode: This mode delivers similar results, but activation and configuration are quite easier. This method uses PHP for the cached content instead of compiling the files. This may result in a bit slower experience as compared to expert mode. It’s still considerably faster for the overall website experience.
