Switch from one photo to the next takes 20 seconds

[hchandless]

13.2 was a rocketship on my computer 64gb RAM 2 2tb M.2 drives. 13.3 and 13.3.1 are almost unusable.  Switching from one photo to another in a shoot of about 1000 photos (Catalog has about 150k) takes 20 seconds or more. It was instant in 13.2. Exporting 100 JPGS take 5 times longer at least. Using things like the crop tool in the develop module is so laggy that it is almost impossible to use. It was like liquid glass in 13.2. 

Please, fix. Not doing a whole summer like this. Don't make me switch editors.

Did you try removing/renaming your previews.lrcat already like I suggested? Without the existing previews, there's nothing that LRC will have to update. It will only render new previews when you access a folder/collection of photos (when the thumbs are visible in the grid).

[Mark Power]

Hi Alex. I did and it made absolutely no difference because the issue - in my opinion - isn't anything to do with the previews/lrdata folders. I am 100% certain that LR is simply re-writing ALL of the XMP files in the catalog (presumably with slightly a different format than previously). You can see it in the various folders on disk, the XMP files are gradually being updated (and tagged with the date they were updated). It seems to be randomly doing it - folder by folder. It is not doing it in the order they were added to the catalog, but it is doing it. This has definitely been initiated by the upgrade of the catalog.... it's nothing to do with me or my preference settings in LR itself, they are set for manual updating in an attempt to maximise performance. Unfortunately, it appears that this isn't happening as a background task either, since looking at the Task Manager appears to show that the activity is just an up-front task within LR just running as an app.... which I think explains why various random tasks such as cropping and masking are being affected so badly and so randomly, LR isn't prioritising these over the XMP updating; it's trying to run them side-by-side. LR seems to be hogging all of the processing power of the PC, but to be fair I'm not running much else.

[alexskunz]

It's odd, I agree. I have "Automatically write changes to XMP" set to ON and did not experience this, but I did delete my previews.lrdata with the 13.3 update, so perhaps mine's been updating all of them too, just not all at once (I haven't looked, but I would have noticed a performance hit like this for sure, with ~47k photos in my catalog).

The fact that LRC does update the XMP whenever something new is added to the Develop module (such as: Generative Remove, Lens Blur, Content-Aware Remove, Point Color, Color Grading vs Split Toning, etc. etc.) without also bumping the Process Version is known, and has been cause for much grief (if you use Publish Collections). I can only guess that it is a side effect of updating the preview structure.

FWIW, I have "discard 1:1 previews" set to just 7 days, and my previews.lrdata is currenly ~200gb (using a 5k monitor).

[Mark Power]

That background "process" that is clearly going on has now been apparent for over TWO FULL DAYS and shows no sign of stopping. My catalog has about 130k photos in it. My PC is by no means slow.... it's way above the minimum spec for LR to work.

I have another two catalogs (customer photos) that total about another 300k, which implies I'm still in for quite a lot of pain!

Why can't there be some form of information displayed during the "process", indicating exactly what is going on and how far along the line to completion you are. I have no idea what's happening or how long it will take.... the only information I have in the obvious accessing of drives, which tells me nothing. It's there when I have LR open, it's not when I don't! There appears to be no pattern to the bottlenecks and stoppages that happen whilst trying to use the software. It just appears to be slowing at random points and I just seem to be letting things run in the hope that the background activity will eventually stop and things will be OK. However, if it's taking this long with 130k photos, how long with the other catalogs....? It's still chugging as I write this.

[jo sch]

Assuming that the background process is the problem, you could try changing its priority in Windows.
Either higher and then perhaps let it run overnight, or lower if you want to work at the same time.

- Go to the Processes tab in the task manager to adjust process priorities.
- Right-click on the process you want to adjust and select "Set Priority."

Good luck

Don't forget to backup

[Mark Power]

Thanks, Jo. However, it HAS been running overnight.... twice! I'll follow up on the advice you give re. prioritising processes.... but this seems to suggest that nowadays being able to use LR involves a Masters Degree in computer science - which it shouldn't. I'm a professional photographer.... not an IBM contractor. It should be a case of just click on the LR icon, import, process the photos using the [not inconsiderable] skill that I have and then exporting the resulting final image to my client. If I wanted to occasionally wanted to spend a couple of weeks completely re-jigging my system architecture I'd get a job as a contractor, the money's way better!!  🙂

[yamato7]

How about creating a new user and using that?

[TOKU]

I came to this forum to write a post and I see that this topic has already been discussed more than once... What's the deal with this program, I can't work, the computer slows down every now and then, everything freezes, I'm frustrated with working with such software and I don't know what to do... Has anything helped you? I have a slightly better computer than you, but I'm about to throw it out the window, I can't work. Unless you have 5x more time and more nerve resources.

[sharpeyes]

I too have a very slow somewhat unresponsive latest version of LRC. I have a Mac Studio, M1 chip, 30gb memory and have found it very fast until now. Sometimes 5-20secs to change to next image. It has become unworkable. I have made a few changes I've seen mentioned here but no difference. It doesn't any longer do what it use to do prior to the latest LRC upgrade and reminds me of yesteryear computers when 5-20secs may have been considered fast.

[sharpeyes]

Yesterday this for me corrected itself. How I dont know but it appeared back to narmal without any known updates!

[alexskunz]

Just out of curiosity: how many photos do you have in your catalog, and for how long did you experience the slowdown after the update? Did you let LRC run idle 24/7, or just normal usage?

[jo sch]

You are absolutely right. I have been using LrC for many years as a hobby photographer and it has never been fast. On such a powerful machine, I expect everything to take less than a second, except for AI stuff, export and import.
But the 13 runs no worse than the 12 for me. In such a complex world, a bug like that is hard to find.
Perhaps Adobe should significantly expand its beta tester base and QA.

[Kimberly38066793u06b]

Anyone else having issues after the recent updates? LR Classic running super slow and then experiencing some images having crazy colors and shapes etc all over ...

HELP!!!!

[KR Seals]

Search this forum for slow lightroom classic issues and you will see all the recent posts about it. There is no point for another thread about it.

Take a look at this thread.

[Tramela34465397juvv]

I can't use my LrC cause extermely slow! I have a lot to do and really need a solution.

Last update nvidia drive, core i5, 16gb ddr4 and catalog on SSD disk!

Still not working here so i'm on v12 ...

[sharonj84589972]

i am having the same issue, taking hours and hours to edit a simple sports shoot because it is all soooooo slow, costing me money in the long run

[Mark Power]

Not sure what advice I can give you.... other than some people have gone back to v12, which isn't acceptable in my book. Adobe should be making some announcements on this, I think. There's clearly an issue with the introduction of AI components into the software.

That's my case... I rolled back to v12.5 because on my Ryzen 9 5950x v13 was slower than v12...

I am having the same issues with the catalog and development being unresponsive. 

It takes 60 seconds to add a pick flag

It takes 60 seconds for a development action to take place. 

Adobe, help! this has rendered the software unusable
