adkoen on "[Plugin: Autoptimize] Very slow pageload after install"

Hi Frank,
thanks for your quick reply.
I'm running on an automatic wpengine cdn, I thinks it's maxcdn. Do I need to enter something in the field CDN Base URL?
If I get it right the css etcetera is minified upon first request? If so, If so I first load some pages, and then empty the caches of my cdn.
best regards,
Koen.
