My favorite WordPress cache plugins that I use

FlyingPress & LiteSpeed Cache are both my favorite WordPress caching plugins.

I recommend:

• FLYINGPRESS for websites based on nginx and Apache
• LITESPEED for large websites with Object Cache & Litespeed Web Server

I personally primarily use FlyingPress on client websites and Litespeed on WooCommerce sites (with larger stores). I generally advise against WP Rocket unless you need to get things done quickly and don't have much time to spend configuring the plugins.

But you should take the time…
