makes some enfold theme based websites extremely fast

i tried a lot caching plugins for customer websites.
as i use updraftplus as backup and migrating plugin i thought, why not also use their related caching plugin.
on two of my enfold-based websites i turned any caching and minifying off in the theme settings and let wp-optimize do all the work.
even with the free version it made some of my websites extremely fast with gorgeous results in google pagespeed insights.
