WordPress Cache Enabler Plugin Review


With over 26% of the internet now using WordPress, the need to speed it up has increased more than ever. It’s not only bloggers using WordPress now but everyone, from small businesses to large news sites (like time.com), and even enterprises. You could say that WordPress has really become a way of life for people. So today we are going to be reviewing the WordPress Cache Enabler plugin, which focuses on improving your WordPress performance.


What exactly is caching?


To put it simply, caching is a way to serve your content in WordPress faster. There are different types of caching. When it comes to the Cache Enabler plugin it focuses primarily on disk caching. It takes your pages and on the backend creates static HTML files and stores them on your server’s hard drive. This is much faster than a default WordPress install because it avoids the core, plugins, and database processes. And all of this happens automatically, you don’t have to do anything.

Additional Cache Enabler Features

The WordPress Cache Enabler plugin is developed around being able to simply install it and go. However, it does offer some additional features such as:

  • Minification of HTML and Javascript (basically this takes out blank space in your code)
  • Automated and manually option to clear cache from WordPress dashboard
  • Viewable size of current cache in dashboard
  • It supports multisite and custom post types
  • Supports responsive images via the srcset update in WordPress 4.4

Unique Features

Cache Enabler also has a few unique features that other plugins currently don’t. The first is that it has the ability to serve up WebP image files in WordPress. This was the first WP plugin in the repository to offer this. If you want to use this feature you have to combine it with the Optimus Image Optimizer plugin to first convert your images to WebP. What are WebP files? This is a new image format created by Google. WebP lossless images are 26% smaller in size compared to standard PNGs.

The other unique feature of the Cache Enabler plugin is that it focuses on the new HTTP/2 protocol. To take advantage of HTTP/2 you have to be running over HTTPs. Basically this protocol speeds up TLS connections. Most caching plugins will offer features to combine files, called concatenation. The Cache Enabler plugin doesn’t offer this because with the new HTTP/2 protocol this can actually harm your performance. So this plugin is looking towards the future and ditching old performance optimization tricks!

Speed Tests

So how much does the Cache Enabler plugin actually help your WordPress website’s speed? We ran a test on a domain and here are the results.

Without Cache Enabler

We first ran a couple tests without the Cache Enabler plugin installed. And here is the average result. Not too bad, and this is on a pretty optimized website already.


With Cache Enabler + WebP

Then we installed the Cache Enabler plugin with WebP enabled and ran some more tests. Here is the average result.


As you can see it decreased our load times by a whopping 45.5%! It also cut our page size down by 35.47%. So using this plugin is really a no brainer, especially since it is free.

How to Install Cache Enabler

Checking Cache

Once you have installed the Cache Enabler plugin you might want to figure out how to see if it is actually working. You can easily do this by right clicking view page source in Chrome. Scroll to the bottom and you can see that it adds a comment in your HTML code with a timestamp. Also, it is important to note that it doesn’t cache if you are logged into your WordPress dashboard, so launch a different browser or go incognito if you want to test.


Or you can run a website speed test to see the difference.
