    Lightroom performance decreases with every update

    BottledLightsPhotography Level 1

      Dear folks @ Adobe,

      I've been using Lightroom for years now but instead of getting faster and more streamlined the whole thing becomes slower and slower with every update. I am running an 4.4GHz i7 with 16GB of RAM, 3 fast SSD drives and a GTX 1050 Ti GPU. I am currently working  on a very small catalog file with only 300-400 images. However, I use a 4K display for image editing. Hardware (GPU) acceleration is enabled in LR.


      - It takes ages to load photos when I click them
      - The spot removal tool takes incredibly long to finally mark a spot after I've clicked, and even longer to find a sample to substitute the marked area with.
      - Sometimes when the Lightroom window is open and active, CPU load on all cores is between 40% and 60%, even when I don't do anything. CPU load immediately drops below 10% when I switch to another program and stays low until I perform any action in Lightroom

      - Again, the spot removal tool sometimes marks areas that I have never clicked on, usually long lines across a major part of the screen.

      - Whenever I press the R key in development mode to crop an image, the image I used the crop tool on before appears for the fraction of a second. Why is that, it is just distracting.



      Over the last 12 to 18 months my workflow in Lightroom (which hasn't changed) takes at least 50% longer than it used to. That's just not acceptable in a professional environment. Of course I tried re-installing everything, that, however, did not really solve the issue. I have the impression that whenever I install an update, Lightroom becomes slower. I'm still using my 5D mk III cameras, so my RAW file size has not increased over the last 4 years.


      - And yes, I have read your article about improving performance but I did not find any solution. In fact, one line really impressed me:

      "To increase performance on such displays, reduce the size of the Lightroom window, or use the 1:2 or 1:3 views in the Navigator panel."

      Honestly, you want me to use a smaller area of my monitor for image editing? Are you making fun of me and all the other professional photographers out there spending thousands of $ or € on large high resolution screens?


      I know at least two colleagues in person facing and complaining about similar issues with Lightroom. Please do something about that really poor performance - and please do it fast.
