WP Fastest Cache is one of the popular free cache plugins for WordPress.

Using Cache plugins you can easily speed up your WordPress website. After configuring the WP Fastest Cache plugin, my site loading time was been reduced to 1.5s in the Gtmetrix test. Currently, I am using the FlyingPress plugin to speed up WordPress website.

The WP fastest cache is quite easy to set up as compared to the W3 Total cache plugin. This plugin also has an option to link your CDN like Cloudflare and StackPath which will further improve your WordPress site loading time.

So, in this post, I have shared the Complete WP fastest Cache plugin Settings with CDN (2022).

CDN has your site load faster as it will host your site on multiple servers around the world. You can link your StackPath CDN, Cloudflare, or any other CDN provider.

You can even use both StackPath CDN & Cloudflare CDN.

In DB you can clear your database files like post revisions, trashed content, trashed & spam comments, etc which will also help your site load faster.

If you are using a free version of WP fastest cache, you can’t use this feature. But don’t worry, there is a free plugin called WP optimize. This plugin also clears your database and reduces your database size. 

WP Fastest Cache Premium Vs WP Rocket

WP Fastest Cache is a great Free Cache Plugin. This plugin also has Paid plans which start from $49.99. This is a one-time payment & you will receive a lifetime update. 

If you compare it with WP Rocket, then they have some additional features like hosting Google Analytics locally, Hosting Google Fonts locally, Video Optimization, etc which WP Fastest Cache plugin doesn’t have. 

In terms of pricing for both of these plugins, plans start from $49, but WP Rocket doesn’t offer free lifetime updates & support. You have to renew it annually to receive updates & support.

Overall, WP Rocket is a better speed optimization plugin than WP fastest cache. But if you don’t want to pay every year, then you can buy WP fastest cache premium version.
