What is Caching?

A cache is a high-speed data storage layer that stores a subset of data, typically transient in nature, so that future requests for that data are served up faster than is possible by accessing the data’s primary storage location. 

Caching allows you to efficiently reuse previously retrieved or computed data.

Each time a user visits your website, WordPress fetches information from the database and then runs several other steps before the web page content is loaded. And if every content of a giving page is to be reloaded every time a users request the content, it will tremendously slow down your website, especially if many people are vising at the same time.

But if you have a caching plugin installed a configured properly, each time a user requests a page, a copy of it is been temporary store in and then served to all users who make a request to that same page, thus skipping the step of requesting from the database.

4- WP Super cache

WP Super Cache is another free popular WordPress caching plugin. It includes gzip compression, page cache, cache pre-loading, CDN support, advanced-cache preload, etc.

This plugin serves cached files in 3 ways (ranked by speed):

  1. Expert. The fastest method is by using Apache mod_rewrite (or whatever similar module your web server supports) to serve “supercached” static HTML files. This completely bypasses PHP and is extremely quick. If your server is hit by a deluge of traffic it is more likely to cope as the requests are “lighter”. This does require the Apache mod_rewrite module (which is probably installed if you have custom permalinks) and a modification of your .htaccess file which is risky and may take down your site if modified incorrectly.
  2. Simple. Supercached static files can be served by PHP and this is the recommended way of using the plugin. The plugin will serve a “supercached” file if it exists and it’s almost as fast as the mod_rewrite method. It’s easier to configure as the .htaccess file doesn’t need to be changed. You still need a custom permalink. You can keep portions of your page dynamic in this caching mode.
  3. WP-Cache caching. This is mainly used to cache pages for known users, URLs with parameters and feeds. Known users are logged in users, visitors who leave comments or those who should be shown custom per-user data. It’s the most flexible caching method and slightly slower. WP-Cache caching will also cache visits by unknown users if supercaching is disabled. You can have dynamic parts to your page in this mode too. This mode is always enabled but you can disable caching for known users, URLs with parameters, or feeds separately. Set the constant “DISABLE_SUPERCACHE” to 1 in your wp-config.php if you want to only use WP-Cache caching.
