What is Caching?

  • Cache: a small area in a computer’s memory that stores all the recently used data and information.
  • Caching: a process in which site’s images, files, pages, web objects are stored on the computer’s local hard drive. So, whenever a user enters your website and asks for any sort of information, the browser accesses all its cached files and displays the result.

How Caching Works?

If your website gets a decent amount of traffic, it puts a load on the web hosting server that you are on, thus, slows down your page speed. What caching does is it creates a static version of your website that does not require going to the database to retrieve information. So, when someone visits your website, the web server is able to display the information that they are looking for faster. It is because now it does not need to go to the database to pull the information.best wordpress caching plugins

WordPress Caching Plugins Compared

In order to get a better idea of the performance of all these WordPress Caching plugins, we used various testing tools, divided into two groups; site grading and timing tools.

1. Site Grading 

Consists of tools provided by GTMetrix, Yahoo, and Google. These tools do not really judge a site on speed, but instead, on quality factors. Server latency, use of browser caching, CDNS, domain sharding, Gzip compression, the location of scripts, optimization and minification of CSS code and javascript, optimization of images are some particular factors that these tools look on.

GT Metrix and YSlow – Both of these are tools that are based on Yahoo’s performance guidelines. They score a site from 1-100 based on their grading result. GT Matrix and YSlow are considered to be very useful as grading tools; however, they are much more sophisticated and effective when it comes to measuring. They are the best when in finding clues on the improvement of your site’s speed.

Page Grade Test

Below is a table showing the results of a test which we made by using the above-mentioned tools i.e. YSlow, GTMetrix, and Google.
