What does “Cache” mean?

Let’s start at the beginning, the word “cache” may sound like Chinese to many people and, if we try to explain it technically, it will still sound like Chinese to many people. 

Therefore, we will try to explain it in a non-technical way and for all audiences.

The cache systems are usually responsible for keeping a copy of data processed to use later when needed without having to process them and get them every time.

When a cache system is working, response times are greatly reduced (in addition to the consumption of resources ) and with that, it is possible to streamline the entire process part.

Caching systems are not miraculous and, depending on the website they are applied to and how dynamic it is, they may or may not be more effective.

On the other hand, the “cache” or saved preprocessed data can be stored in different places: RAM, disk, etc.  Depending on where they are stored and the hardware of the server, the cache can be more or less effective.

Another essential step to optimizing through the W3TC configuration is minimizing the number of unnecessary assets to reduce the weight of your page. In this way, you can guarantee a shorter loading time by selecting the “Minimize” option of the plugin, selecting the “Automatic” mode.

With the application of this measure, you will be reducing the loading time, size, and the number of CSS and JS files and automatically eliminating unnecessary data from CSS, JS, and HTML from feeds, pages, and posts.

4. In the section called ” Database Cache ” you must “Disable” this, the rest remains by default. This allows you to cache the database to reduce post, page, and feed creation time.

For this feature to offer benefits it is necessary to deactivate it, because the database of this plugin known as W3 Total Cache saves each query made. And in turn, this data is stored in an administrator known as MySQL. That is why it is better to use the object cache.

5. In the section called “Object Cache” you must check the “Enable” box, the rest remains by default.

Taking into account that the cache is a memory that can be accessed through settings. Everything to speed up the process of loading a page and the object cache is not something very different.

Simply, for WordPress, it is an already built-in tool but with limited functionality as it is the default option. While the other options external to WordPress manage to retain data through many more pages.

Enable this important setting in W3 Total Cache and enjoy the benefits it offers to your WordPress page. One of them is to speed up the different requests to your database to make different queries. You just have to insert your modified cache script in your directory and that’s it.

6. In the section called ” Browser Cache ” you must check the “Enable” box. This reduces server load and reduces response time by using the cache available in your site visitor’s web browser.
