What is Cache and Why it is importance?

What is LiteSpeed Cache (LSCache)?

LSCache is built from the ground up and integrated into all LiteSpeed server products. It can:

• dramatically speed up dynamic website content (like PHP pages)
• provide more efficient handling of static content (like images)
• reduce server load

Understanding Caching

What is cache?

Cache is a mechanism for storing data in such a way that it is easier or faster to retrieve than the original source. Web application sites consist of dynamic pages that are built with PHP or some other method. The pages of these sites don’t exist anywhere in the file system; they are constructed on-demand by the web app, and then served to the visitor as HTML. Generating these dynamic pages can be resource-intensive and slow.

Why cache is important?

A cache makes everything run faster and it improves the performance of the system. By storing local copies of website files, your browser only needs to download that information the first time someone visits and can load the local files on subsequent visits.

Website cache eventually empties out after a certain period of time. However, you might wish to clear the website’s cache to display the updated version if the content has changed and needs to be reflected immediately.

Before we proceed, let’s take a look at what scores Google PageSpeed Insights gave the mobile and desktop versions of the tested website before setting up LiteSpeed Cache:

Once LiteSpeed Cache for WordPress was configured, both versions achieved perfect scores:

On the other hand, its optimization features can be used with any web server, including OpenLiteSpeed, Nginx and Apache. these features include image optimization, CDN (Content Delivery Network) integration and CSS/JS modifications.
