Hi!

I am a software developer. Recently, my Lightroom CC (version 4.2 - 20210301-0713) is very slow . A close look at activity monitor reveals that the app consumes too many threads and memory (attached photos) which freezes the app.

@Rikk Can you help me forward this to the development team?

Thank you so much!

New Studio Ultra with 128GB ram (20cpu 48gpu), current versions of all OS (Monterey v12.3.1) and software (LR v11.3.1, PS v23.3.1). Despite setting memory limits in Photoshop preferences (and what little I can control with Lightroom), both PS and LRc will routinely and quickly gobble up ram to the point that I get an OS error ('out of application memory'). LR is the bigger offender.

This just happened to me with LR open and being used (cloning headshots, maybe 60x/image), PS closed; ram usage shot up to 98GB over the course of maybe 30 minutes, and then I got the OS error, requiring me to close LR. Oddly, Activity Monitor showed 0.0 bytes of memory being used. PS set to 55% memory limit; when open editing large panoramas, it will often exceed that and head toward 100+GB; unfortunately LR does not allow you to limit memory usage, although it's a moot point since PS does not respect the limits set, anyway.

Three screenshots of Activity Monitor from the last several days included below.

This is becoming way worse than the years-old memory leak on Intel machines (longtime user, coming from 2021 5k iMac i9 w/128GB). One would think that having ample ram would help issues like this, but it seems to matter not.

How come are we still adressing this? How come this is still an issue?

It seems even worst now, even without GPU aceleration LR just keeps wanting more and more RAM, makes no sense.

Just giving this a +1. I've had the issue on my old Intel iMac and had hoped moving to an M1 would help. No luck; using an M1 Pro with 16GB RAM and I'm having the exact same situation. LR Classic uses 15-16GB RAM and won't let it go until I quit and restart.

Adobe--this is so frustrating. I've posted about this memory leak on these forums before.

New Macbook 16 with 16GB RAM. I iinstalled the Lightroom (Cloud) from the adobe creative cloud. When I open the software the RAM is pegged to the point where I can't open anything else without massive warnings about SWAP usage because RAM is pegged.

If I close everythiing else and just use LR, I can get by but that's not acceptable, definitely something wrong with its memory usage.

Providing a little more context which may be helpful.

First: Lightroom 5.1 (20211204-1710-0e71941 Build). MacOS 12.2 Beta (21D5039d). (Yes, it's a beta. The same problems occurred on 12.1. I upgraded to see if it fixed them; it didn't.)

Test. I put 30 D7500 NEFs in a folder in Lightroom and Apple Photos, none with any existing adjustments, and then ran the following test: start at the first image, hit the 'auto' button for adjustments, scroll through each image as quickly as possible and at the last one again hit 'auto'. So effectively that's browse a folder of 30 images and adjust two. And when I say folder I mean it's a normal dumb folder in my main library with only these images in it. Before running the test I switch to the folder, quit the app, then restart it so it opens directly there with, hopefully, no other images loaded in memory.

And one additional test for Lightroom: I ran it again with 'Use Graphics Processor' in Preferences > Performance switched to 'Off'. For the first run it was set to the default of 'Auto'.

Results: Photos consumed 1.14 GB of memory; Lightroom with use graphics processor switched to auto used 7.6 GB; with it switched to off, 1.45 GB.

Hypothesis: there may be a leak or bug with the M1 series and their unified memory architecture when LR's use graphics processor setting is switched to auto.

Also, you can see clearly from the memory pressure graph where I opened Lightroom.

I'm running into memory pressure from Lightroom too on an M1 Pro 16GB. Here's a screenshot showing it ballooning to 8.8GB after opening it, browsing through a few folders, and lightly editing two files (no local corrections). This is the only app that seems to put the Mac under this kind of stress.

Hey there,
I am very upset with my new iMac 2021 16/256 machine. I just use adobe photoshop and lightroom classic which taking too much ram and using swap memory. I talked with adobe support team they weren't able to fix my issue.
Any idea? what i can do in this case?
Thanks

How much memory is "too much"? How much do you want it to take up?

I have seen occasional reports of memory leaks; but other than that, Lightroom Classic uses as much memory as it needs.

What version NUMBER of Lightroom Classic? We need the version NUMBER and not words like "latest" or "up-do-date".

I cna concur that there seems to be some kind of memory issue. I was using Lightroom CC for about an hour and noticed the fan on my M1 Max 14" MacBook Pro starting to spin (a extremely rare occurance I've noticed). I checked that activity monitor and Lightroom was using 32GB of memory. I was able to quit and relaunch and it was back down 6.49 GB, but quickly climbed to 8.15 without me doing anything at all in the application. I'll keep an eye on it.
