W3 Total Cache is a WordPress plugin that optimizes site performance. To install it, search for the plugin and click install, then activate it. Some permissions may need changed to 777 or 775 temporarily during install. General settings to configure include enabling page, object, and browser caches. The cache preload section should be configured to prime important pages. Browser cache settings like last-modified headers and expires headers for assets should also be set.

- 13. Setting the Garbage Collection Interval depends on the amount of traffic to your site. The busier the site the lower the interval. We’re going to use the default 3600 It is important to clear cache or you may run out of disk space. That’s the importance of setting this interval correctly.
