    Lightroom use too much memory and CPU

    gawakoto Level 1

      Lightroom all of a sudden takes a very long while to export photos.  When i checked my activity monitor, LR is hogging my cpu and memory. This is the first time it ever happened.

          Hi gawakoto,

           

          Sorry that Lightroom is using high memory while exporting images.

           

          Could you please let us know the version of Lightroom you're using and how many images at once are you exporting?

           

          Thanks,

          Akash

                Thanks for update. What are the specifications of your computer? Also, could you please provide us a screenshot of the Activity monitor illustrating high spike in CPU usage while exporting from Lightroom?

                 

                Also, please provide us the Help>>System info details from Lightroom.

                 

                • In Lightroom, select Help > System Info from the menu bar.
                • In the System Info dialog, click Copy.and paste it here.

                    Thanks for providing the details. Please try unchecking the option "use graphics processor" under Preferences> Performance menu in Lightroom and check if the app still uses that much memory in the Activity monitor?

                    Also, test create a new catalog and check how the application behaves.
