Still, wish to know more about the same? Then read on our full review of the three plugins below.

Features

WP Super Cache Features

Preloading

WP Super Cache allows you to create cached files for the posts, categories, and tags for your website for preloading. Preloading posts, categories, or tags reduces the amount of workload on your site, thus cutting down on server workload and resulting in reduced amounts of bandwidth used. This feature is very useful. Perhaps keep in mind that after enabling this feature, the plugin will take some time before it finishes preloading the posts or categories. This is because the preloading will visit every single post on your website one by one, just like what a visitor would do. So the more the number of articles on your WordPress site, the more the time it will take to get the job done. Besides, you also need to garbage collection so that older cache files are not deleted by enabling “Preload Mode.”

Garbage Collection

Preloading your posts, categories, or even tags can fill up your caching directory, thus taking up space on your server. To get rid of this, you will need to enable garbage collection. That is only useful if space is limited or billed by capacity. Garbage collection can be done on a regular basis, so you do not have to remember doing it by yourself. Some excellent garbage collection features include a scheduler, which allows you to set how often should the garbage be cleared and the Cache timeout feature that lets you specify the period after which files will be regarded as stale.

Content Delivery Network (CDN)

A Content Delivery Network, popularly known as CDN is a network of computers located around the world that act as servers to your website. So a visitor coming to your site from Australia will be served by a server next to them and not the default server. As a result, your website loading speeds will be immensely increased. CDNs serve static files like images, Javascript, and CSS files that result in increased website speeds.

WP Super Cache is integrated with OSSDL CDN off-linker to bring native support.

Rest API

WP Super Cache also has REST API endpoints for accessing the settings of this plugin. Although they have not specified what exactly this does or how it works.

Custom Caching

There are also custom caching options available for those who love getting their hands dirty with code. But don’t shy away if you are not into code; you can ask your developer to set up things for you.

W3 Total Cache

Accelerated Mobile Pages (AMP) support

AMP is an open-source framework developed by Google to bring a faster browsing experience on mobile. Websites with AMP support load instantly while using mobile platforms – both Android and iOS, etc. If you have an AMP supported site, W3 Total Cache is here to make things even easier for you.

Platforms supported

W3 Total Cache supports several server types. Whether you use shared hosting, virtual private or dedicated servers, and dedicated servers or clusters, you name them. There are all supported by this caching plugin.

CDN

Like in WP Super Cache plugin, W3 Total Cache also has a Content Delivery Network for fast loading speeds no matter where your visitor is located. W3 Total Cache includes a content delivery network (CDN) management with Media Library, theme files, and WordPress itself.

Caching features

W3 Total Cache plugin boasts of several caching features that play an essential role in faster web loading speeds. There is caching of minified and compressed posts, pages, CSS, and JavaScript on either memory or CDN. In addition to that, there is also caching of feeds like the site categories, tags, comments, and even search results. Other cached features include caching of search results pages, database objects, objects, and fragments in memory. You can also control browser caching using cache-control, future expires headers and entity tags (ETag) with “cache-busting.”

W3 Total Cache plugin caching methods include the following local Disk, Redis, Memcached, APC, APCu, eAccelerator, XCache, and WinCache.

Minification

This plugin also includes the minification of various objects. There is a minification of posts and pages, as well as feeds. Additionally, there is also minification of inline, embedded, or 3rd party JavaScript and CSS with automated updates.

JavaScript Grouping

W3 Total Cache allows JavaScript grouping. With this functionality, you can categorize JavaScript by a template like home page, post page, etc. with embed location control.

Mobile Support

Other features available on W3 Total Cache include; Direct Importation of post attachments to the Media Library and CDN, Caching statistics for performance insights, Extension framework for customization e.g., Cloudflare, Reverse proxy integration via Nginx or Varnish, cache purging, query string updating via WP-CLI support

WP Rocket Features

Lastly, we have WP Rocket. Here are all the features on WP Rocket caching plugin;

Page Caching

Page Caching enables faster loading of website pages. WP Rocket has this handy feature that is activated when you activate the plugin.

Cache Preloading

This feature is also available in WP Rocket. Cache preloading enables faster page load speeds by caching web pages, posts, and even categories. But unlike in WP Super Cache, WP Rocket crawler simulates a visit to preload the cache, so this makes it easy for indexing of your website in search engines.

Sitemap Preloading

In addition to cache preloading, WP Rocket also has sitemap preloading functionality. The plugin preloads all your URLs in your sitemap. Even if you don’t have a sitemap already, this plugin automatically detects Jetpack, All in One SEO and Yoast SEO sitemaps.

Static Files Compression

WP Rocket also includes minification. The plugin compresses your website’s HTML, JavaScript, and CSS files for faster loading speeds. The concept behind this is pretty simple – Lighter files means faster load time!

Images on Request

Images are a good thing since visitors like seeing things visually. You already know a picture can mean a thousand words, and that is why including images on your posts is crucial. However, if you are not keen, images can reduce your website loading time. WP Rocket handles images on posts differently. It only renders images upon request. That is, images are loaded only as your visitor scrolls down the page. This technique is pretty standard, with most websites on the internet. Even the most popular ones like YouTube, Facebook, Yahoo use this technique for improved loading time.

GZIP Compression

Although WP Super Cache has not included this in their list of features, the plugin has this functionality as well. GZIP compressions result in the faster rending of website pages through optimization of browser rendering, thus saving on bandwidth.

Database Optimization

WP Rocket also includes database optimization, which removes bloat, thus improving website load speeds. There is also an option to schedule these cleanups for convenience.

Google Fonts Optimization

Google font optimization ensures fewer HTTP requests, thus providing faster web loading speeds.

Removal of Query Strings from Static Resources

For a better GT Metrix Grade removal of query strings from static resources. What’s good is that cache-busting will still be retained.

Lazyload

Lazyloading is a similar thing to what W3 Total Cache refers to as ‘Images on Request.’ This feature ensures that images only load when a visitor scrolls down a page, thus resulting in faster loading speeds.

Defer JS Loading

Defer JS loading ensures that JavaScript files are only loaded after the page is fully rendered. As a result, page loading is improved.

Cloudflare Compatibility

WP Rocket is compatible with Cloudflare. The setup process is simple since WP Rocket supports Cloudflare natively. With Cloudflare compatibility, you can manage your Cloudflare cache and even enable development mode directly from your WordPress dashboard.

CDN

Like the other caching plugins in this review, WP Rocket also supports the most common CDN platforms like Cloudflare and MaxCDN. Using a Content Delivery Network is a good practice for improving web loading speeds through the reduction of HTTP requests.

DNS Prefetching

DNS prefetching is a handy feature for reducing the time of DNS resolution from external websites.

Mobile Detection

This feature is available on Wp Super Cache and W3 Total Cache plugins, as well. It makes it easy for you to offer mobile visitors all the website features via a one-click button.

Multisite Compatibility

For those with a website sub-directory, subdomain, and domain, you will love the compatibility of the WP Rocket caching plugin.

eCommerce Friendly

If you own an eCommerce store, you can also enable faster web speed by using the WP Rocket plugin. It supports eCommerce plugins like Easy Digital Downloads, WooCommerce, JigoShop, iThemes Exchange, or WP Shop. WP Rocket excludes the cart and the checkout pages from caching.

Multilingual Compatibility

The Verdict

Finally, we have reached the conclusion section. After delving into the three WordPress caching plugins, we are pretty sure there is a premature conclusion at the back of your mind. But before we let that mature, here is our take on the same.

Among the three plugins, it is clear that WP Rocket has the most functionality as a caching plugin. Some features available on WP ROCKET Are not available on the other two plugins. WP Rocket stands out firmly over the other plugins thanks to the easy setup process, google font and database optimization, defer JS loading, cache preloading, and eCommerce friendliness. With these features, WP Rocket is rich in functionality. Developers will also love the plugin with this developer-friendly plugin.

WP Super Cache is another excellent alternative. The plugin is free and is baked in with several functionalities, though not enough. But since the plugin is all free for anyone to use, there are no complaints since some features available have to be paid for anywhere else.

The Winner

Between the three caching plugins, it will be unfair to compare the three on similar ground. This is because some plugins like WP Super Cache are all free while others are premium. So we will choose a winner based on various factors. Firstly, WP Rocket is the best plugin for those who want to get rich functionality inside a caching plugin. Yes, it has no free plan, but it is worth paying for. On the other hand, WP Super Cache is the best free plugin if you do not have a budget set aside for purchasing a plugin like WP Rocket. You can’t beat free, and WP Super Cache still champions this philosophy.
