Photos app is unbearably slow (M1, Big Sur)
I have a 120 GB Photos library on an external USB 3.0 drive (formatted as MacOS extended (journaled)), connected to my M1 Mini and the latest Big Sur. Photos is so slow that it's almost unusable. I've run speed tests on the drive and it seems fine, and there's plenty of free space on the drive.
Is there any known way to speed things up, or is Photos kind of abandonware by Apple?
Mac mini, macOS 11.4
