When it comes to fast loading WordPress sites, caching is crucial. A well-optimized page cache can dramatically improve load time for visitors and reduce the load on your server. It’s a win-win situation! However, not all page caching solutions are equal. A simple plugin search for “caching” on WordPress.org will return thousands of results. But WordPress caching plugins aren’t the only options available when it comes to page caching your site. In fact, WordPress caching plugins often don’t perform as well as a server-based solution such as Varnish or Nginx FastCGI.
