Why does LrC use so much memory on Apple Silicon?

[Henry Richardson]

Why does LrC 12.5 (which is an Apple Silicon native program) use so much more memory than LrC 12.5 on Windows Intel (and maybe Mac Intel)?

Over the last couple of years, but particularly in the last few months, I have noticed that LrC just seems to use up an ungodly amount of memory on my 32gb MBP. I think 12.4 and 12.5 on Apple Silicon use up more than I remember 12.3 using, but I do not have 12.3 on my Mac anymore so I am just going by memory. With 12.4 and 12.5 after editing for a while (16mp and 20mp photos) I fairly often notice that LrC is using 21-28gb of memory! But even when not using that much it is almost always using 14-20gb after a bit of editing. I am just using the controls in the right side Develop panel and occasionally I may do some masking, but not a mask for every photo for sure. No panoramas, no Denoise AI, etc. Just basic stuff. My recollection is that with 12.3 I rarely saw it using more than 14-15gb.

I also know that LrC uses much less memory on my 32gb Win10 laptop. It still had 12.3 on it so I spent the last few hours today doing something I detest doing and that is some tedious, boring, careful comparisons and writing down the results. I rebooted and only had LrC running in all cases below. I tried doing the same sequence of editing of the same photos using LrC 12.3 and I recorded the memory usage. Then I updated to 12.5 and rebooted. I then did the exact same sequence again with 12.5.

Then I did the exact same sequence with LrC 12.5 on my MBP. Before I began I rebooted and the only thing I had running was LrC. By the way, I was using the same catalog and photos with both computers. Before starting I had copied the current catalog to the PC's internal SSD and all the photos are on an external SSD.

By the way, the formatting from the dpreview forum editor is not good. It is perverse and almost impossible to get all the spacing right. :-(

Here are the specs of the two computers:

Dell 15.6", Windows 10 22H2
i7-8565U, 4 cores
Nvidia Geforce MX250 2gb
Intel UHD 620
32gb RAM
512gb SSD + 2tb external SSD

and

Macbook Pro 16.2", Ventura 13.5.2
M2 Pro 12/19
32gb RAM
1tb SSD + 2tb external SSD

After rebooting each of them and before starting LrC I let them sit a few minutes to make sure both had done all their initialization and the OS memory use had settled down. On the PC I used the Task Manager and on the Mac I used the Activity Monitor. This is how much memory each was using before starting LrC. Not particularly important, but since I had written it down I will include it here.

PC: 4.5gb

Mac: 6.03gb

Then on the PC I started LrC 12.3 and let LrC get all initialized by waiting a couple of minutes. While in the grid view and sitting idle it was using 1.95gb. Later after I updated to LrC 12.5 and rebooting I started LrC again and while sitting idle in the grid view it was using 2.05gb. I then filtered using the Metadata only my Olympus E-M1 II raw files that were unedited and then checked the memory usage. For 12.3 it was 2.38gb and for 12.5 it was 2.66gb.

I did the same on the Mac with LrC 12.5. LrC was using 8.42gb in the grid view sitting idle. Then I used the same Metadata filter and it was using 7.03gb.

Then I did identical edits on the same 7 E-M1 II raw files (20mp) using 12.3 and 12.5 on the PC and 12.5 on the Mac. All had basic edits and a few also had a mask. Here are the results below. Yes, I know this is a lot of data and most will have no interest in it. The bottom line is that LrC on Apple Silicon uses much more memory than LrC on Windows Intel. I do not know the situation with LrC on Mac Intel, but I suppose it is closer to the Windows Intel memory usage than the Apple Silicon memory usage. Anyone here checked?

After each file name I show how much memory LrC was using while sitting idle in the Develop module after doing the edit for the file.

Are these numbers for the entire computer or just the Lightroom application? Maybe you included that but I missed it.

Henry,

I am going to go out on a limb and say that the AS uses the memory to finish the tasks quickly. After it's done does it purge out? If so, I think it's using the system available to it efficiently. I would love to see my PC's use all available to it to do things fast.

I think this is at least part of the issue - you aren't really comparing the same thing - the systems use memory differently and the monitors measure different things.

My MacBook Pro has 16GB of memory and in normal use LR shows about 8GB including with various masks. The total memory used on the system is around 16GB.

Last year my M1 Mac Mini 16gb/512gb did not have this LrC very high memory usage using slightly older versions of LrC. It did use more than my Windows PCs though. My recollection is that my 16" M2 Pro MBP 32gb/1tb using LrC 12.3 and before did not have such huge amount of LrC memory usage either just doing my normal, simple editing of 20mp, 16mp, and smaller photos. I really noticed it starting with 12.4, but I cannot be absolutely sure of that because I no longer have 12.3 on my Mac.

I sometimes get yellow memory pressure using only LrC 12.4/12.5 when inexplicably LrC is using 25-28gb for no apparent reason. I did not see that in the past using older versions of LrC on this 32gb Mac and my earlier 16gb Mac, both with Apple Silicon.

No one else is seeing this behavior on Apple Silicon with LrC 12.4/12.5?

Henry,

I am going to go out on a limb and say that the AS uses the memory to finish the tasks quickly. After it's done does it purge out?

This info I wrote in the OP was after waiting for several minutes:

Dell, LrC 12.5:

Afterwards idle in grid view 4.22gb

MBP, LrC 12.5:

Afterwards idle in grid view 18.24gb

If so, I think it's using the system available to it efficiently. I would love to see my PC's use all available to it to do things fast.

Do you notice that LrC 12.4 and 12.5 use a lot more memory on Apple Silicon? I have noticed no speed improvement from 12.3 to 12.4/12.5.

As I wrote, I sometimes see LrC 12.5 using 25-28gb! I am not editing big photos, maximum size is 20mp. But after basic, simple editing for awhile I sometimes see LrC 12.5 using tremendous amounts of memory and my memory pressure changes to yellow.

Hi Henry,

I don't have an as mac yet. If there is no speed improvement, I am guessing mac uses large amounts of memory to keep the speed up. I am thinking this way from basic computing theory. if something is lacking in the cpu power/gpu power I am guessing apple is masking it by pushing the ram to its limits to make sure it does not slow down while doing the edits.

Okay, I see where you are misunderstanding. I guess you do not understand what LrC means. LrC means Adobe Lightroom Classic. I am talking about Lightroom Classic on Apple Silicon. I am not talking about Apple Silicon. For example, I did not say anything about TextEdit, Calculator, XnView, FreeFileSync, etc. using an inordinate amount of memory on Apple Silicon. I am specifically talking about Lightroom Classic version 12.5 (and 12.4). This thread is not about Apple Silicon in general. It is about Adobe Lightroom Classic 12.5 running on Apple Silicon. It is not Mac using lots of memory, it is Lightroom Classic 12.5.

 

[Henry Richardson]

I think this is at least part of the issue - you aren't really comparing the same thing - the systems use memory differently and the monitors measure different things.

Can you give more details on how the program memory used shown in the Task Manager and Activity Monitor are different?

My MacBook Pro has 16GB of memory and in normal use LR shows about 8GB including with various masks. The total memory used on the system is around 16GB.

I assume you are using LrC 12.5? Up to LrC 12.3 on my M1 Mac Mini 16gb/512gb and 16" M2 Pro MBP 32gb/1tb I noticed nothing that seemed outlandish. Starting with LrC 12.4 though I started seeing memory usage routinely be near 20gb, but fairly often go up as high as 28gb doing basic editing on 20mp and smaller photos. Not the first photo, generally after editing a few dozen in a session. Sometimes it would finally drop down some from the highest levels after awhile if LrC was sitting idle, but still be near 20gb. I do not think I ever saw this behavior with 12.3 and earlier. See my post:

https://www.dpreview.com/forums/post/67250989

Usually when LrC 12.5 has gobbled up so much memory and memory pressure is yellow I have to quit LrC to free up the memory and then restart it.

You should ask about it on Adobe Lightroom forum

I understand perfectly. That piece of software is using LOTS of ram on your AS mac. I am saying that with AS mac, that piece of software uses that memory to complete tasks quickly. I understand it's not about AS mac in general, I am saying that optimized LRC for AS is using LOTS of available memory to finish tasks faster.

As a test I tried rebooting - this time with Mac Mini M1 16GB LR12.5 - making simple edits to 20 FujiFilm RAF files one after the other and memory reported by Activity Monitor to LRC reached around 8GB - more than I'd like but useable so long as I don't have any other memory hog running.

1) I see the same behavior, means LrC 12.5 using 25 - 28 GB of memory over time, on my MBP M2 Max with 64 GB of RAM, even when just doing light editing work.

2) I cannot say how LrC behaved before version 12.4, as before I had an older computer that could not run anymore the actual LrC versions.

3) I even saw LrC 12.4 using around 56 GB of memory, means all RAM available considering the system uses around 8 GB, on my new machine when I once, out of curiosity, set LrC in Preferences - Performance - Use Graphics Processor to Custom, with all three options (Use GPU for display, Use GPU for image processing, Use GPU for Export) activated, instead of the standard Auto setting! I then found an article that explained this behavior as a problem resulting out of the unified memory architecture of Apple Silicon.

I am not a computer specialist, therefore may be absolutely wrong, but considering

- the behavior described above under 3)

- the fact that also Adobe DeNoise AI seems to have a problem using the NE on Apple Silicon

I could “imagine” that the overall high memory usage of LrC in its actual version(s) could be based on not optimized utilization of the Apple Silicon architecture. But again, I may be wrong…!

I have both an intel mac and an Apple Silicon mac using LRc.

One reason it uses more memory on AS is because LRC (and photoshop) use a large amount of the shared unified memory for its graphical acceleration, whereas on intel this is done by the gpu with its separate vram.

You can prove this yourself by disabling the graphical acceleration in LRc in preferences performance.

Yes, Adobe said a few months ago that Ventura introduced a Neural Engine bug that prevents them from using it with Denoise AI. DXO announced the same thing about an Apple Neural Engine bug in Ventura. Apparently, even though there have been several Ventura updates since all this came to light many months ago Apple has still not fixed it.

I could “imagine” that the overall high memory usage of LrC in its actual version(s) could be based on not optimized utilization of the Apple Silicon architecture. But again, I may be wrong…!

I do not want to go to all the bother to reinstall LrC 12.3 (I assume there is a way) just to confirm that my recollection is correct that the memory usage was not as massive as in 12.4 and 12.5. I just hope that the next LrC release (probably in November) will fix this. I was hoping the same thing for 12.5, but when I got it in August I saw that it was still not fixed.

Hi,

Just a basic question, is the memory being used by LRc causing you any issues running other programs?

If not, then I don't really understand why you're concerned.

Alot of people keep system diagnostics and monitoring on screen all the time. I used to be one of those people but was fixating on numbers constantly. If temps or component usage deviated one bit, I would start freaking out. I turned all of that off and use my system as I intended it to work. I care less about ram useage, cpu temps etc as the system is working as intended. If it wasn't, it would give warnings to any issues.

The ram usage in this case is normal as the software in question requires it. AFAIK, Apple will increase / decrease ram usage as needed to any optimized software. I have seen people who has safari using over 8gb of ram as the system has it there to use.

It's part of the optimized Apple Silicon platform. It's there to use. If the OP had other software open, not as much would be dedicated to LrC and more would be used for other things.

Exactly!

I used to design embedded HW & SW systems and I knew everything about everything. Now it's so complicated I just use the darn computer!

I had a 16GB M2 where LRc took nearly all the RAM. Now I have a 32G M2 and it still takes nearly all the RAM. Never had a problem with either machine running multiple apps at the same time.

Just enjoy it!

100%. I am not an engineer. I do know, after reading enough about the AS systems, that that is how they work and punch above their power weight.
