Great friendly support

Was using W3 Total cache and changed to WP Fastest cache. Had problems and started using Hummingbird for the asset optimization without the caching while using the WP Fastest cache. Then one day disabled WP Fastest cache for debugging and re-enabled and all my problems disappeared.

Deleted hummingbird and deleted W3 Total Cache. Believe there was left over stuff with W3 total cache when I installed the WP fastest cache. Note I used the freeware of the WP Fastest cache for a while before upgrading to the premium. Might have had something to do with it.

My site is getting 96 on Google page speed insights for desktop with a load time of 1.8 seconds while the mobile is getting 74 with a load time of 4 seconds. Not bad for a photography web site. One thing to note that fully loaded at 4 seconds. The first paint is 1 second for both the mobile and desktop. Also on Gtmetrix I have 90% for a pagespeed score and 83% for Yslow score. However have not optimized since I moved to Amazon AWS Cloud Front.

What I would like to see is more flexibility with the WP Fastest cache that allows you to preload fonts and other CSS, JS scripts. Furthermore would like to have more flexibility in moving theme files to the footer or inline CSS. Maybe an advance mode ?

So this plugin is fast.
