  • Extremely efficient and fast disk cache engine, even greater results with SSD based servers

  • Automated and manual clearing of the cache
  • HTML, CSS and JavaScript minification

How does the caching work?

This plugin requires explicitly minimal setup time and no configuration at all. No coding, no configuration – install and activate, thats all!

The WPCacheOn has the ability to create two cached files. First is in plain HTML and the second file is gzipped (gzip level 9). Those static files are used to deliver content faster to your website visitors without any database lookups or gzipping because the files are already precompressed.

Stay tuned for new features!

I am always trying new cache plugins and compare them with other plugins and their results. All of the options in GTMetrix that are related to plugin cache level are on their maximum! Plugin do not have many options and it is very easy to use. The fact that there are that good results of the plugin without additional options is awesome! This plugin is great if you would like performance without the boring configuration. I give you 5 stars! I will be following this plugin for new features and version.

Hello, thank you for the awesome speed plugin! Before installing your plugin, we have make speed tests with GTMetrix and have F in performance score and 5 seconds of loading time. After installing and activating your plugin, the performance score was increased from F to B and the loading time lowered to 2 seconds! Probably best part was that we have only activated the plugin and do no changes and results was better. Good work guys! We will definitely use your plugin in future.

I just made a review of different cache plugins and was very curious about this one. I compared GMetrix results with Swift Performance Light and CacheOn did not have a good score for YSlow test (less than 80%). So I’m not impressed. But it works without problem on the test site and options (very little) are very convenient to check. Better than no cache plugin but I think other well known plugins will do a better job with proper configuration.
