I am using AVADA Theme. When I activate this plugin, the theme's "typography" settings mess up. You can not use the theme's typography settings. And it had a conflict with another essential plugin which is woocommerce and "Learndash-Learning management System" plugin. So I decided to delete it. I don't recommend it. It is unpredictable... And no change in my site performance after 1.5 months. The dashboard is also not informative. Just a messy graphic which you can get no solid info. Anyway, since it caused negative effects on my site's other working parts, I deleted it from my both websites.
We installed the plugin which was very simple (only 1 click) and left it for 30 days. I logged back in today and was pleasantly surprised to see the comprehensive stats on display. Prior to installing the app our page speed was 4.19 secs and now the average page load time is 1.7 secs. The metric they are using is the Time To Interaction which seems reliable.
Works great! Phenomenal and personal support!
