How to Install and Setup WP Super Cache Plugin

All content in WordPress is served dynamically and generated using PHP. The content  is then fetched from the MySQL database and sent to the user’s browser using PHP. When the server runs a PHP script to fetch the content, it consumes a lot of resources in terms of CPU usage and memory on the server computers. This will be a limiting factor for your website performance, especially if you have a high traffic blog (which you want). Caching, on the other hand, generates a static HTML file of every WordPress blog post, which alleviates the requirement of executing PHP scripts to serve content to your readers. With caching enabled, things run smoothly and quickly on the side of your users because there are no more complex database communications and script execution. This helps your WordPress blog load faster in any browser. With PHP execution operations at a minimum because of caching, you save a lot of precious CPU and memory usage for your WordPress server. WP Super Cache is therefore one of the most important plugins for WordPress, as it enables you to do just that.

The following steps will help you to install and setup WP Super Cache quickly and simply.

1. Log in to your WordPress dashboard and click on Plugins on the left menu panel. Then select Add New.
