High Sierra photo editing slow

I upgraded to High Sierra on a Mac Pro 2015. I notice Photo editing runs slow. Any edits that I make lag for a few seconds before showing up.

MacBook Pro, iOS 11.0.2

Same... Photo retouching VERY slow. My library all on top spec 2014 iMac (Fusion drive). Nothing in iCloud. Only happened after High Sierra upgrade - all background processes completed as far as I can tell.
