Caching is one of the most important innovations of the internet. It is because caching allows us to decrease the load of the server by serving the cached data. Joomla is a very established and popular content management system. And, almost all the content management system provides some kind of caching system that allows us to serve more customers with fewer server resources.
If you are not using the cache, you can save lots of money on your server infrastructure. If you don’t know what caching exactly does, let me explain it to you in brief. Whenever a visitor visits your site, your site has to process data with the programming language as well as it has to query your database server to get the required data. And it happens every time a visitor visits your site, no matter if the content is the same for all the requests.
What caching does is, it saves the rendered content for the same request. Then, it will serve the same rendered content to other visitors visiting the same page with the same content. It means that once the cached data is saved, the server will not request the database server to fetch data until the cache is expired. You can set the cache expiry as per your requirements. If you regularly update the content on your site, the cache expiry should be shorter.
