5 Best WordPress Caching Plugins for 2020

WordPress does not have a system for speed optimization by default. That’s why you need a powerful plugin that speed up WordPress with technical and advanced features, yet accessible to everyone.

While most blog posts (including ours) will share the top most popular WordPress Caching Plugin, it is important for you to understand that you never want to use more than one WordPress Caching Plugin on your website.

With that said, let’s take a look at our expert pick of the best WordPress Caching Plugin and tools.

WP-Optimize

WP-Optimize is a revolutionary, all-in-one WordPress performance plugin that cleans your database, compresses your images and caches your site.

WP-Optimize cache feature is built around the world’s fastest caching engine. This simple, popular and highly effective tool has everything you need to keep your website fast and thoroughly optimized!

It does it in three clever ways:

  • It allows you to clean and optimise your database.
  • It gives you the option to compress your images.
  • It allows you to cache your pages, for super fast load times (read more caching information below).

Extensive tests show the cache feature alone can make WordPress sites at least as fast as any other caching or speed plugin available and often faster. But when you combine the cache with the database optimization, image compression features and minify, the speed difference with alternative solutions is significant.

With minimal configuration, caching your site with WP-Optimize is easy to do thanks to a load of useful features, including:

  • Cache preloading to ensure the cache is always ready and loaded.
  • Gzip compression of HTML, JavaScript, and CSS to reduce site load time.
  • Device-Specific cache to ensure the optimized page version is always served.
  • Advanced cache exclusion rules, so that you can cache almost anything by excluding logged in users, specific URLs or cookies.
  • Browser Cache to instruct client browsers to reuse cached resources (HTML, CSS, JS, images) if no changes were made since the last request.

Overall WP-Optimize brings the best cache and optimization technology together in a single seamless plugin to make your WordPress site fast, lean and efficient.

WP Super Cache

https://i2.wp.com/ps.w.org/wp-super-cache/assets/banner-772x250.png?w=1290&ssl=1

This plugin generates static html files from your dynamic WordPress blog. After a html file is generated your webserver will serve that file instead of processing the comparatively heavier and more expensive WordPress PHP scripts.

The static html files will be served to the vast majority of your users:

  • Users who are not logged in.
  • Users who have not left a comment on your blog.
  • Or users who have not viewed a password protected post.

99% of your visitors will be served static html files. One cached file can be served thousands of times. Other visitors will be served custom cached files tailored to their visit. If they are logged in, or have left comments those details will be displayed and cached for them.

The plugin serves cached files in 3 ways (ranked by speed):

  1. Expert. The fastest method is by using Apache mod_rewrite (or whatever similar module your web server supports) to serve “supercached” static html files. This completely bypasses PHP and is extremely quick. If your server is hit by a deluge of traffic it is more likely to cope as the requests are “lighter”. This does require the Apache mod_rewrite module (which is probably installed if you have custom permalinks) and a modification of your .htaccess file which is risky and may take down your site if modified incorrectly.
  2. Simple. Supercached static files can be served by PHP and this is the recommended way of using the plugin. The plugin will serve a “supercached” file if it exists and it’s almost as fast as the mod_rewrite method. It’s easier to configure as the .htaccess file doesn’t need to be changed. You still need a custom permalink. You can keep portions of your page dynamic in this caching mode.
  3. WP-Cache caching. This is mainly used to cache pages for known users, URLs with parameters and feeds. Known users are logged in users, visitors who leave comments or those who should be shown custom per-user data. It’s the most flexible caching method and slightly slower. WP-Cache caching will also cache visits by unknown users if supercaching is disabled. You can have dynamic parts to your page in this mode too. This mode is always enabled but you can disable caching for known users, URLs with parameters, or feeds separately. Set the constant “DISABLE_SUPERCACHE” to 1 in your wp-config.php if you want to only use WP-Cache caching.

If you’re not comfortable with editing PHP files then use simple mode. It’s easy to set up and very fast.
