Before heading towards the uses of WordPress cache warming and the plugins used with it, we just need to understand the concept of cache warming.

Warming up cache is a technique used by websites to ensure that actual visitors always have access when needed.

What Is Cache Warming?

Instead of serving the first visitor, cache warming operates by preheating the cache for users. You will fully understand how cache warming functions and how it enhances site performance by the time this blog post is over.

It is very important to understand why cache warming is important before explaining it. The key advantage of cache warming is that it speeds up web page loading. Quick web page loading makes better user experience and improved visitor experience.

What is the Purpose of Cache?

A Cache can be defined as an ordered structure that saves values for quicker lookups. Cache works by storing different references in a quick search database. For this quick search, the cache must store values.

Now that we know why caching is crucial, let’s examine what it is and how it may make your website load faster.

Your web browser requests the server to create a web page for you each time you visit a website. Along with the HTML element that makes up the page, other files such as images, content, styling, and others are stored on the server.

A single webpage is created by your browser contacting the website’s server up to 100 times. If you don’t utilize any caching, you will have to perform those requests repeatedly each time you visit that page.

Furthermore, every visitor to that page submits the same questions that are called requests. The website’s server becomes slower and less responsive when many users are accessing it if the requests are not cached. By storing a copy of the finished web page in numerous locations, caching offers a marvelous remedy.

Following are the cache warming plugins and scripts you can use to enhance the performance of your site.

Cache Warming Plugins and Scripts

When caching plugins are used, pages are often served from a cache after a visitor views them for the first time. Subsequent visitors can then access the cached copy of the page for quicker page loads.

This is effective for websites with significant traffic, but if the site is more of a brochure with low activity, its occasional users would notice a slower page generation because the cache is not fully utilized.

By pre-warming the pages cache – which entails having a site crawler crawl your site to prime cached copies of the pages – cache plugins can circumvent this problem and ensure that both new users and repeat visitors can enjoy the same quick page loading times.
