satriyo WroteColonafter upgrade themes with latest, I got notification from WP fastest cache that they have update. driven by curiosity, I update wp fastest, disable all other caching engine (cloudflare, redis server). surprisingly, it deliver the best result so far...
here is my test this morning :
with my end user experience on chrome desktop (via mobile connection tethering) deliver the full rendered page under 4 seconds consistently on front page and less than 3 second on other pages.
Oye @Satriyo buddy, the smart hours function "Open & Closed" working on WP Fastest Cache plugin ah? I'm actually using the premium version of WP Rocket cache plugin, it boost the speed of my site but the smart hours function gets stuck. So i had to deactivate that plugin. If the smart hours function is working for you when WP Fastest cache is active, i will switch to that plugin asap.
@Satrio & @MMM - Thanks for your always best recommendations.
