LR Classic regularly uses 10.35 gig of memory on my M1 Mac.  I don't think the problem started with 11.1 though, not sure. The catalog is not large at all, and I'm editing a group of 12 RAW photographs.  See snapshot of Utility Monitor.  Is this memory leaks or considered normal?  I'm up to date on the OS, evverything really.   Thank you.  (PS: I was going to start a new thread on this but can't find the "new thread" command alas.)

Hi Art M.

LRC shouldn't be using 10.35G of memory! LRC (ver 11.1) uses 1.2 G of memory on  my system. Even Photoshop uses less than 5G. I don't know what the problem is, but that sounds like too much memory usage to me. Good Luck!

How much memory LR uses is related to how much you have available (as well as your settings, particulary in PS preferences). I have 128GB in my new (nearly loaded) Mac Studio, and LR and PS commonly use 50-60GB each, and I've seen LR get up to 95GB prior to freezing. Apple's powerful new machines are rending bare Adobe's poor coding and ongoing bugs that have plagued the programs for YEARS. Adobe seems not to be able to (permanently) get rid of the GPU memory leaks in LR, while adressing features and bugs that do not relate directly to the performance degradations that we've all be suffering through for years. Importing/exporting may have gotten a bit faster with the 'new' (cough!) Apple Silicon versions, but little else has changed; waiting up to 10 seconds to render at 1:1 is just plain silly, and affects my day-today massively. 

 

If only there were an alternative that was a true contender to replace LR...

Excellent information.

My only question or concern is regarding standard-size previews. The heading says to keep them "as small as possible," but then says stay closest to the screen resolution. With so many 4k, 5k, and 6k monitors, this equates to rather large preview files and thus large Lightroom Catalogs, which can slow down a system.

Advice?

How disable/uncheck the option to "Generate Previews in parallel" is expected to speed up operations?

These images do not match what is on my screen. I go to prefences and it is just graphic card information.

If you are seeing this-

2022-09-17 08_25_39-PreferencesDialog.jpg

Then you are using Lightroom (-Desktop. The 'Cloud' Version).

The images given for "Quick Tips", and the hints, are for Lightroom-Classic.

 

Regards. My System: Lr-Classic 12.0.1 Photoshop 24.0.1, ACR 15.0, Lightroom 6.0, Lr-iOS 8.0.8, Bridge 13.0, Windows-11.
