You are also worried when using a web browser or any app with auto save function or any app that relies on a database right?

Just like every website has a 1000+ 45 MP DSLR RAW images right?
Big difference between those in swap usage....

Besides the hyperbole that magically makes the M1 have double the memory, 16gb or higher is still necessary for many heavy usage apps. Reminds me 10 years ago when Apple was trying to defend the 2gb soldered base memory on the macbook airs by relying on some magic memory compression. Several years later the 4gb machines were fetching more than the price delta of the memory upgrade (which is very rare if you follow upgrade/resell pricing)

I'm worried my M1 MacbookPro won't last a year.
On this rate I'm writting 1TB/day

This is the usage of editing 75 24mpx raws from A7iii in LR under 2hr with mixed usage between apps (chrome, spotify etc)

It wrote 205Gb, ~190gb of swap (taken from kernel number). I had a kernel panic before and I was already at 250gb writes into the day. So I will average when working full time 1TB/day.

M1 with 8GB is not meant for anything that's not web and pages use. Lame... My MBP 2017 might be slower, but at least can work on the go if you need and will last years...

This is SO BROKEN. I even closed LR.
I will need to find another app to work while adobe fix this *****.

Usually, I'd consider this kind of digging into stats when all works well as a bit dumb but actually... this is truly a bit worrisome.
I never analyzed it on my old MBP(2016) so I have no comparison but definitely M1 MBP has quite intense swappiness (indicated by kernel_task writes) and running Lightroom results with absolutely CRAZY DISK WRITES by kernel_task. Today in last 5 hours I've been mostly running Slack + Safari today and then opened Lightroom Classic twice just for testing and I've had 450GB of writes!

It seems like Lightroom requests all the memory it can have and on M1s kernel is very generous with giving the app what it wants.

I don't doubt SSDs in Apple products are quite high quality and I'd never worry about things like that but with writes of 1-2TB+ per day when using Lightroom this looks really troublesome :x

It does sound like something not quite right. Is this with catalog and all masters on system disk?

Might try moving it off and seeing if it drops. Q whether it is swap driving this or lightroom.

Both catalogue and masters on the internal drive.
Looks like swap as it is `kernel_task` doing the writes but I'll try later with catalogue and masters on external.

EDIT: Literally 1 minute of looking through 20-25 Sony A7 photos in Lightroom Classic and kernel_task wrote 10GB to disk according to Activity Monitor.

Personally I think 8gb too little for heavy use of Lightroom.

But the amounts you're citing do seem excessive. (Not any specific one but trend)

I'm inclined to think something going on with Lightroom but only a guess. I presume it stops when not using lightroom? Have you quit out of everything else? What is lightroom showing as memory usage? (I may have missed in some of your previous posts, apologies if redundancies in my questions)

I agree. That's why I have MBP 16GB/1TB :)

No, at all questions are appropriate especially as there are no previous posts of mine on the topic ;)

With light usage kernel_task writes some but nothing as crazy that happens when Lightroom Classic is launched.
It's really weird - seems like some combination of Lightroom and OS (Rosetta?) problems as at the same time. Activity Monitor doesn't indicate that Lightroom uses that much of virtual memory AND there's still some RAM left.
All in all, it's a pity cause Lightroom runs super smooth but it might be really destroying SSD at the some time

I'll provide more concrete numbers in the afternoon cause I have to do some real job now ;)

Lightroom does write quite a lot of course when in use, esp if doing previews, importing, etc., with various adjustments applied (doesn't it re-build previews unless instructed to leave them on disk?).

I'm using lightroom a bit right now (not stressing) and lightroom shows a fair amount of writes (to external disk) but that's not being reflected in the kernel or swaps (lots of memory). Other processes are writing of course but each reflected under their respective processes.

So it does sound to me like something unusual going on here. May be hard to diagnose unless you can find others having the same problem. It does happen that there are bad interactions. Another thing to check is the cache settings in Lightroom preferences/performance, although they should be pretty obvious. Smart previews might be a culprit, possibly (I'm not a lightroom expert, recently arrived in lightroom).

Did a little poking about this morning. Grouping/stacking some photos (16MP Olympus u4/3), couple HDR merges, a few develop tweaks. Rebooted beforehand. No other apps open.

@blaraka isn't crazy. :p

LRC definitely is chewing up more memory / swap than it has any need to be doing.

Yes, that clearly indicates something is going on that shouldn't be. I have a large catalog open on lightroom now, large RAWs, lots of edits, etc., and some active work going on. LR has 2.3gb of memory in memory panel.

I seem to recall getting LR to take up perhaps ~7gb of memory with some large import and edit operation ongoing. Why it would jump to 15gb as you have is beyond me. (One diff, I'm still on mojave)

But I won't pretend to know why this would be caused by Rosetta. Some extra memory, sure, but the data hasn't changed. (I don't recall seeing Big Sur/Intel users complaining but haven't been following any LR specific discussions except here)

I've restarted.

Launched nothing except Lightroom Classic.

Lightroom Classic process sits at around 13-14GB of memory but inspecting the process shows that Virtual Memory grows steadily as you operate in "Develop" tab.
This is reflected in writes to disk done by "kernel_task".

In short, 15 minutes of scrolling through images and applying some presets at Random and I'm at whooping 20GB written to disk by kernel_task ;)
It doesn't happen when scrolling images in "Library" and basically doesn't persist when I do nothing or close Lightroom Classic.
Makes me almost think that I'd like this thing slowed down so I'm actively encouraged not to scroll through images in the folder in develop mode. Even if that would be happening I'd never be able to trigger so many writes in such a quick time on my 2016MBP as it was just too slow :D

II''try Capture One (running through Rosetta) and Lightroom CC (M1 native) later today to see if those are causing anything of sorts. I don't want to switch but if those are fine there's at least hope it can be solved.

I was hoping memory usage would improve with Universal code, but my Mac mini 8gb is still hitting yellow too much and getting sluggish on importing the last wedding I did with over 1000 pics. My 16gb Intel machines nor my 16gb M1 MBA hit the yellow at all. Planning on returning this MM 8gb when my 16gb finally arrives some time next month....

But do you notice any degradation in actual usability or performance?

Your memory pressure is still well within the green zone, and that is a better indicator of utilization than the raw numbers. I've noticed several reviewers start to say that the M1 runs as well with 8GB of RAM as Intel systems do with 16GB. While I feel that may be some level of hyperbole, I do think that UMA allows the system to allocate and use RAM more efficiently, and that is probably where these benefits are coming from.
Click to expand...
It's definitely hyperbole. One thing I have yet to see are memory usage comparisons between a comparably configured Intel and M1 system. While I would expect some variation I wouldn't expect 2x or 1/2 memory variation. Perhaps someone who has both can perform this type of test?

It's the 14-15gb that jumps out. Similar work right now, less than 3gb on an Intel system.

What is virtual memory? You can see it when you double click on Lightroom process.

Since the earlier stats, I'd exited LRC and left it be. I've reopened LRC, browsed some images, slightly rotated / straightened a couple Olympus TG5 RAW, and did a 9 image panorama merge (Oly EM5mk2 16MP images).

EDIT - did a couple five-image HDR merges and here are the results...

I've responded to your thread.
I've also opened another one on Lightroom Classic support forum: https://community.adobe.com/t5/ligh...ead-writes-to-ssd/m-p/11684831?page=1#M216645

Not of the same files, I will look into this weekend. But the swap/writing of the other files weren't near what I'm currently getting...

It's swap/rosseta related...

@h4ck1nt0$h3r I've just checked Lightroom CC and it's all the same as with Classic.
Crazy writes from `kernel_task`. I don't think we can blame Rosetta anymore. I guess it is what happens when resource monster that Lightroom meets easygoing swappiness of M1 Mac kernel... Seems terrible.

Not sure what I think about it anymore. I enjoy this computer that I might just try to use it and hope it won't break in few months.
