WordPress caching plugins overview
WordPress caching is a great way for enhancing your website's efficiency. If your site is receiving a lot of traffic, you can use WordPress caching plugins to improve the performance of your website.
WordPress caching is the process of reusing previously requested files or created data (or requests such as database queries) to speed up new requests when a website is requested frequently by various visitors.
So, with WordPress caching plugins your hosting server can have those files prepared and serve them to your users every time they visit your website. When delivered from the cache, files are served without calculations usually necessary for those files to be served - request -> serve from cache.
In this article, we will view some of the most used WordPress caching plugins that will help you in the mentioned above:
The plugin provides full-page caching, with the help of its exclusive server-level cache and other
optimization features. This simply means that the plugin saves static snapshots of your site's
pages. It can do so because dynamically generated pages are mostly identical each time they
are created. Instead of having the visitors wait for WordPress and PHP to assemble the pages
for each request, a page cache will quickly serve the snapshots.
This plugin shows up in the first place when you type CACHE in the WordPress Add New plugin

WordPress is a powerful tool for content management and website deployment. With it's scalability and complexity required for most website to function as designed, you should test all available caching options according to your use case. In some cases, some themes were known to malfunction with certain caching plugins but, work properly with others.
