How is your WordPress site doing? How long have you been running it by now? After a time, things may not run as fast as before. The amount of content uploaded after years or traffic’s increase can make your WordPress sluggish. If you want to power your site’s speed, caching plugins are a great choice.
How do caching plugins work?
WordPress is a dynamic content management system. Every time a user/client explores your website, a process must happen to load each page’s content. Once a page is requested, every part of it (posts, menubar, ads, etc.) is queried by WordPress to the database. To fetch a page’s elements means many calls to this database, code executions, and time.
