Dear support team,
I have recently started a new project, rebuilding a website that is getting old and slow.
Before I start the new version, I wanted to make some quick speed improvements, mainly by using HB and Smush Pro.
When I try to Bulk Smush images, Smush Pro times out. Same goes for the "directory smush".
This multisite is quite huge and there are several thousand images to improve.
I wandered how necessary was image smushing, since I enabled the Smush CDN.
Is there a way to launch a full image optimisation on all folders, running in the background as a cronjob or something ?
Also, I installed HB in order to perform some cleanup and quick improvements (I won't dive into asset optimisation, as there is more than a hundred websites to test).
Is there a way to add "cleaning orphan meta-data" in the DB cleanup tool ?
Also, I granted support access because I'd like to know if you could help me remove ZenCache and replace it with HB caches ?
Is there a way, in a WP multisite, to identify unused themes ? (filtering out those that have a child-theme in use)
Thank you very much for your help.
