HOw big is your monitor (in pixels, width and height; do not tell me inches)?
How big are your photos in megapixels? (do not tell me megabytes)
Are you doing lots of brushing and/or lots of spot healing on your photos?
Welcome to the increasing slowness of the app they call Lightroom. Rumor has it there is a new update coming soon that fixes the insane slowness.
Monitor: 2560 x 1600
Photos: 5304 × 7952
Yes, I do a lot of brushing and spot healing.
What do you think about it?
A lot of brushing and spot healing is a known cause of slowness. Using a 4K monitor and huge original photos (42 MP) makes the problem worse. Your old Mac can't keep up. Some possible solutions:
- Turn off the GPU acceleration in Lightroom (but this could make other things slower)
- Do the brushing and spot healing as the next to last step in editing, and the last step is to turn on Lens Corrections and transforms
- Do the brushing and spot healing in Photoshop or Photoshop Elements, it will be much faster
- Upgrade to a very fast CPU by 2018 standards (although that may not be enough depending on how much brushing and spot healing you are doing)
I have noticed a huge decrease in performance since the 7.2 update, prior to this I had a very fluid and creative environment within Lightroom, but update 7.2 has taken me back 10 years, the computer gives me the timer for 1-2 seconds everytime I do anything and trying to move a brush or gradient now is awful, Adobe what have you done ?? I want to go back to the previous version please. I have an iMac 2017 with i7 processor 64GB of RAM and 512 SSD, so as fast as a standard iMac can be, everything was fine until the 7.2 update, now it is almost unusable !!

You can re-install Lightroom Classic 7.1 from the Creative Cloud App, click the down arrow to the right of Lightroom Classic CC, select Other Versions
Thank's DJ, you just saved me, works fine again, great news, you have made my day. As for Adobe's new performance fix, pufff !
