Question
Lightroom classic became unworkably slow
Hi
I'm a full time photographer working with lightroom for the past 18yrs.
Since recently, I guess after the last update, lightroom became unworkably slow.
It's slow when going to the next photo in the develop module. Sometimes I have to wait +7 seconds before I can even see the next photo.
I optimized my catalog.
I have enough diskspace
