Very, very high CPU usage, since version 13 (now using 14.0.1)

I have been a subscriber to the Lightroom/Photoshop package for over 6 years.

 

I currently use it on two computers, a Mac Mini 2023 and for a little over 6 months, on a Macbook Pro 2019, Core I9 with 16GB of RAM.

 

On this Macbook Pro 2019, Core I9 with 16GB of RAM, it is IMPOSSIBLE to use Lightroom currently.

Over 1400% CPU usage sometimes, never less than 200% !!!!

(see image below)

 

I had an old Macbook Pro 2014, I7 with 16GB of RAM. Last year, with the latest versions of Lightroom, the performance was terrible, but it worked bravely. Due to lack of money (Brazilian photographer, poor South American!), I bought a Macbook Pro 2019, Core I9 with 16GB of RAM. The performance is 1000x worse!

 

This 2019 model must be Apple's biggest failure!

 

Does anyone have any ideas to improve this performance?

    The poor efficiency of the later Intel processors is a big reason Apple chose to switch to Apple Silicon processors, which can do the same work with much less power consumption and heat.

     

    Still, the Lightroom Classic CPU usage looks unusually high on the 2019 Core i9. Try adjusting the settings in the pictures below:

    A. Definitely disable this option. It’s OK to enable it on recent computers with many efficient cores, but on yours it may be occupying too many CPU cores too much of the time.

    B. Maybe disable this option if CPU % is still too high after disabling A.

    C. Your Standard Preview size is set to 3584 pixels. Try reducing the size and quality to require less CPU processing power and time per preview generated.

    D. If this option is enabled, it might take more CPU to process multiple external metadata files compared to writing to the database. But this is probably not a major contributor because it shouldn’t be doing anything at idle time.

    E. Although this might not be a major contributor, see if constant CPU usage goes down if this option is disabled.

    F. Similar to E, constant CPU usage might go down if this option is disabled.

     

    Generally, those options are nice to have on a recent computer with many efficient cores and a lot of unused CPU power. But if you are having problems similar to those on your Core i9, start disabling those options.

        I've been sick for a few days and haven't been reading posts and forums. Thanks for the suggestions, I've already implemented some of them! But the performance is still way below expectations! This 2019 Macbook is really a not very successful project.

         

        Thanks to ALL of you for your help and suggestions!

        Hey, @AndreMotta. Welcome to the Lightroom Community. I'll help you figure this out. 

         

        Try these suggestions:

        1 - In Lightroom Classic > Preferences > Performance & set the Camera Raw caches to 15 GB or more.

        2 - Try resetting Lightroom Classic following the manual method shared here: https://adobe.ly/4aPIWol

        3 - Try disabling the 3rd party plugins and compare if that helps. 

         

        Let me know how it goes. Thanks!

        Sameer K
