How Does W3 Total Cache Work?

W3 Total Cache is a complete framework: caching, minification, lazy-loading, and CDN integration. What’s different with W3 Total Cache is the plugin remedies numerous performance-reducing aspects of any website going far beyond merely reducing CPU usage (load) and bandwidth consumption for HTML pages alone. Most importantly, it’s the only plugin designed to optimize all practical hosting environments small or large.

The main focus of W3 Total Cache is caching all aspects of a website, including:

  • Pages and posts
  • CSS and JavaScript
  • Feeds (site, categories, tags, comments, search results) 
  • Search results pages (i.e. URIs with query string variables)
  • Database objects
  • Objects in memory or on disk
  • Fragments in memory or on disk

Apart from that, it uses caching methods, such as Local Disk, Redis, Memcached, APC, APCu, eAccelerator, XCache, and WinCache

As for the minification & defer, W3 Total Cache uses several open-source tools to attempt to combine and optimize CSS, JavaScript, and HTML. It works by minifying script files including:

  • CSS, JavaScript, and HTML with granular control
  • Posts, pages, and RSS feeds
  • Inline, embedded, or 3rd party JavaScript & CSS with automated updates to assets
  • Defer non-critical CSS and Javascript for faster rendering
  • Defer offscreen images using Lazy Load to improve the user experience

Equally important, the plugin requires no theme modifications, modifications to your .htaccess (mod_rewrite rules), or programming compromises to get started. The options are many and setup is easy.

Please note that prior to W3 Total Cache installation, you need to make sure that you uninstall all other caching plugins. If you do not do this prior to installing, the plugin will have issues upon activation.

What Are the Features of W3 Total Cache?

Some key features of W3 Total Cache included in the free plugins are:

  • Page Caching
  • Browser Caching
  • Database Caching
  • Object Caching
  • Minification
  • Automatic CDN support
  • Lazy Loading of Images/Media

Page Caching

As it should be, W3 Total Cache provides page caching. It is responsible for creating static cache pages for each page that is loaded, so it is not being dynamically loaded upon each page load. Having this enabled will significantly decrease your load time on the website.

Browser Caching

With W3 Total Cache, you can set up browser caching with a time limit. Therefore, every time a user visits a website, the plugin will download all the images, CSS files, JavaScripts, and other static files in a temporary folder to enhance the user experience. This way when the same user goes to the next page, it will load much faster because all the static files are in their browser cache.

Database Caching

There is database caching included in W3 Total Cache to reduce the server load by caching SQL queries. This eliminates the processing time of querying the database. However, this feature seems to put a lot of load on the server. Therefore, we recommend you turn it off. Instead, it ended turning on the built-in SQL caching for you. 

Object Caching

For you who have a highly dynamic website, then using Object Caching in W3 Total Cache will help. This is mainly used if you have complex database queries that are expensive to regenerate. However, this feature is unnecessary for most beginners.


The minification feature in W3 Total Cache simply reduces the size of your static files to save you every single kilobyte that you can. The plugin minifies CSS, JavaScript, and HTML files to speed up the loading time.

Automatic CDN support

Apart from the caching feature, W3 Total Cache also provides CDN support. Moreover, W3 Total Cache has some of the most comprehensive CDN options available out of any caching plugin to reduce loading time. It has direct integrations with StackPath, Amazon Cloudfront, MaxCDN, and more.

Lazy-loading of Images/ Media

One more great feature provided by W3 Total Cache is lazy loading. Lazy loading prevents loading off-screen images until needed, speeding up the overall load time of your website.

Usually, you’d have to install an additional plugin specifically built for lazy-loading. But with this feature in W3 Total Cache, you don’t have to get a separate plugin for lazy loading.

W3 Total Cache Pro

The free plugin by W3 Total Cache has provided great features you need for optimizing your website performance. However, with W3 Total Cache Pro you will get additional features, including:

Caching Statistics

W3 Total Cache Pro provides advanced metrics about your site’s performance that help you diagnose previously unknown performance issues with your site, web server, MySQL, etc.

Fragment Caching

This feature allows you to control the caching times for comments, eCommerce, and other interactive elements. Hence, it ensures performance is maintained, while users see the most up-to-date content available.

Full Site Delivery

Full site delivery is a modern technique to get even faster speeds when paired with a CDN. You can use this feature in W3 Total Cache Pro so your users can enjoy a lightning-fast website.


Besides those additional features, W3 Total Cache Pro also provides other options. You will get Rest API caching, extension support for the Genesis Framework, WPML, and more. Additionally, you can optimize your Google Maps with the lazy load for Google Maps.
