Excellent free and premium versions

I have the premium license now on two sites.. The free version made my site much faster.. Added maybe 15-20 on the score for PageSpeed.web.dev Tested the premium on one site and it added some more, especially to mobile (~10).

I currently have the premium on both of my sites. The settings are simple and easy to change. You have pretty much everything you need there (preload, exclude, clear, etc.). I turned the “Widget Cache” off, because I didn’t like the effect it was having.

FYI, if you have the premium version I recommend checking “Mobile” and “Mobile Theme.” Having a separate cache for mobile is what added the extra gains.. It IS necessary, even with responsive themes.

$50 one-time license fee is doable.. Would definitely look to purchase this on any future sites I own. Definitely experiment with the free version if you aren’t able to buy the premium.
