Setting up a WordPress caching plugin is a must, but which caching plugin to choose? I choose two of the very best WordPress caching plugins and tested them thoroughly. In this guide, I will compare WP Super Cache vs WP Fastest Cache to find out which one is better.
Why I Compared WP Super Cache and WP Fastest Cache?
Speed is one of the most important factors that affect SEO. As an SEO professional, I want my website and all my client websites to be as fast as possible.
For a WordPress website, you must use a caching plugin to achieve better website speed. Now the question is, which caching plugin is the best? There are actually so many of them but I used WP Super Cache vs WP Fastest Cache.
WP Super Cache is created by Automattic, which is a company that created WordPress. WP Super Cache is one of the most popular WordPress plugins and at the top among WordPress caching plugins.
WP Fastest Cache is also a very popular plugin but nowhere close to WP Super Cache in a number of downloads and installs. It has more than 1700 five-star reviews, which says a lot.
I wanted to actually test both plugins on my website and run tests using Pingdom. I also wanted to test them on my client websites. This allowed me to test both WP Super Cache and WP Fastest Cache on different web hosting companies.
How My Website Performed Without Any Caching
Before testing the caching plugins, first I wanted to test how my website performs without any caching plugin. Here is the test result of my website without any caching.
Yeah, I didn’t believe my eyes either. This test result is very bad and will have a highly negative SEO impact. My website was loading in more than 6 seconds. That’s completely unacceptable.
Testing My Website Performance with WP Super Cache
Now I wanted to see how WP Super Cache can improve my website speed. I installed and activated the plugin and set it up. The first step was to turn on caching.
The second step was to enable gzip compression. This is important because it compresses a web page before sending it to users which makes the page download quicker.
WP Super Cache has many advanced options but I only wanted to enable page caching and gzip compression. I looked into minifying CSS and JS but that was not very easy to do with WP Super Cache.
After setting WP Super Cache on my website, I tested it using the Pingdom tool. Here is the test result screenshot.
Yep, this result is much better. My website was now loading under 635 ms. It was now faster than 95% of all websites. That’s amazing!
Now let’s see how WP Fastest Cache compares to such a great result.
Testing My Website with WP Fastest Cache
After installing WP Fastest Cache I went to its settings page. It was simpler than WP Super Cache and I was done with settings in a few seconds.
Note: I don’t have the premium version of the plugin, just the basic free version. I noticed that they have many more options in their premium version.
After the setup, I visited the Pingdom website and ran the test. Here is a screenshot of my test result.
Now, this is astonishing. My website was now loading under 528 ms and it was faster than 96% of all websites.
