A cached file is typically generated after a user initially visits a page. This creates a delay for the very first user who views it.

The preload allows you to create the cache of all the post, page, category, homepage periodically, which helps much in improving future page loads.

How it works

The preload feature stars to work after delete cache.

When the Preload feature calls the urls, the cache of urls are created automatically. When all the pages are cached, the preload stops working. When the cache is clear, it starts working again.

The Preload runs every 5 minutes. If you want set a specific interval, you should take a look at the Manually Preload with Cron Jobs tutorial.
