Clear cache and plugins Usually, they'll recommend a caching plugin, but these plugins aren't compatible on WordPress.com because we automatically provide server-side caching for your site. However, you'll have the option to manually clear your site's cache in the hosting settings. WordPress caching is the fastest way to improve performance. If your site is under attack right now, install W3 Total Cache, WP Super Cache, or Cache Enabler.
On WordPress, rendering or retrieving a page (or post or custom post type) requires that queries be sent back and forth to the database. Now, most of the time, you'll create a post or a page and then not update it every day. Caching creates static copies of your post or page and sends them to visitors. In this way, queries back and forth to and from the database can be avoided, reducing server load.
WordPress has a built-in object cache. WP_Object_Cache is a WordPress class that can automatically store any database data in PHP memory. This way, you can avoid repeated and unnecessary queries to the database. That said, W3 Total Cache is a free and open source WordPress caching plugin with millions of installations.
It has the advantage of being integrated with a CDN and works well for both mobile-friendly sites and regular desktop sites. The plugin also boasts of being a useful add-on for websites with SSL certificates, making it an ideal speed solution for e-commerce stores. Fortunately, an effective way to increase the performance of your site is to use the WordPress object cache. However, since many claim to offer the fastest WordPress hosting out there, how do you decide which company to use? In this post, we'll see.
In any case, a WordPress caching plugin like W3 Total cache will surely improve the overall performance of your site and increase your conversion rates thanks to the performance of that site. Consult the official Cache Enabler documentation when configuring and testing it on your WordPress site. The simplest solutions start with local server caching, while more complex and complicated systems can use multiple caching servers (also known as reverse proxy servers) “in front of the web servers where the WordPress application is actually running”. Consult the official Comet Cache documentation and the community forum when configuring and testing it on your WordPress site.
Using a professional WordPress hosting package can improve your site's response time by up to 50%, which means improving the user experience and increasing your Google ranking. The disk caching engine is quite fast and reliable, while WordPress's multi-site support is an advantage for those with networks of websites. LiteSpeed Cache's advanced features are only compatible with LiteSpeed servers, which doesn't apply to most WordPress sites that use Apache and Nginx. Even on the regular WordPress plugin page, you'll find dozens of links and FAQs to guide you and inform you about caching.
