What can be done to speed up deleting photos?
Deleting photos from Photos for Mac OSX is slow - rarely will a photo delete complete in less than a couple seconds, and frequently they will take 8-10 seconds!
By "complete" I mean the time it takes from when I issue the delete command (regardless of whether I use the keyboard or mouse to issue it) and the time I can start using Photos again.
This delay makes sorting and editing my photos maddeningly slow.
