I just updated lightroom CC to 1.1 (20171201-1016-60550c6 Build). I guess I was hoping for improved performance, but now it's ten times worse, no exaggeration. Trying to move photos from one album to another was always slow and painful. Now it rarely works, or if it does it takes a long, long time for even one or two pictures. It takes a minimum of 15 seconds to copy a picture from one album to another and then another 15 seconds to remove it from the first album. I'm on a 100G broadband connection with Intel i7 8 core processor. My CPU usage is pretty low. So whatever is happening behind the scenes, it's not using much in the way of resources on my machine. It's the service that's slow.
