P: Adding to/Creation of a new Target collection takes minutes unless Sync is paused

[wroublin]

Hello everyone.

I've been using LR for a long time, previously on an intel based Windows 10 laptop. It was a bit slow, but usable.

Now I am using m1 macbookair, both MacOS and LR are up to date and the issue persists.

Since couple versions ago - LR is not usable for me. My collection is huge, has photos on several external hard drives, but i mostly use one, with most current shots. Since 3-6 months my LR is UNUSABLE. I push the B key to add image to target collection - nothing happens. I push it again - nothing happens. After couple minutes - some photos appear in the target collection, others don't, because i pushed the button more than once. It's very annoying. Sync activity goes back to some photos on random external hdd (not currently connected) form way back - i haven't done anything with those photos but there are sync errors for some reason, because why not?

Also - i create a collection - and it doesn't appear immediately.I create another one - after 20 minutes LR wakes up, that the collection I want to create has to have a unique name and boom, the firs one I created magically appears. Seriously - my impression is that this has something to do with syncing - as I sync some collections to cloud to be ableto do some additional culling on my mobile while on the go.

I cannot work like this and instead of having a pleasant experience with culling photos - I am very annoyed and I am unable to work like that. What can i do to make it work smooth again?

no, its not a laundry list, please read the issue description carefully (and if you would stop editing my title to dumb it down - it WAS IN THE ORIGINAL TITLE ALSO) - its all closely related to the background sync operation! Once the sync is complete - the issue disappears - but so long as there is even one image syncing in background (no significant CPU and GPU usage ever recorded for background sync) - then many operations from the "laundry list" start to lag. But it is all tied to the background sync. Also putting the sync on pause does not always help - if there are images in the sync queue Lightroom still keeps churning some sync tasks in the background (same around 100% (one core) CPU usage on mac) - even with sync ON PAUSE!

[DaMoroshka!]

also all my "different and highly-likely (in your opinion) unrelated issues - ALL STARTED at once after the sync engine was revamped in one of the last releases (I guess in 13.3 but you should correct me if I'm wrong). Once the sync engine was updated - IMMEDIATELY I had all those issues - which is in fact ONE issue - basic operations that were real-time instantaneous  before - e.g. click cmd-B to add image to collection, or hit "auto" for auto tone correction  -  all those started to lag atrociously whith background sync active. Even exiting the app is not possible when the "lagging" time is on! Lightroom is in "non-responding" status in the Activity Monitor and you have to wait a minute or two for it to un-freeze and exit.

@DaMoroshka! 

I have explained how the forum works. If you choose to avoid best practices, I cannot force you. 

Since you are already working directly with the Classic team via your diagnostic log, I am going to recommend you wait for them to finish their investigation. I checked with them yesterday and they are still looking into the data you provided. 

I wish you well. 

Thank you for your continued patience.

This thread is now locked. 
For the specific issue of long-time delay when creating a Collection see: https://community.adobe.com/t5/lightroom-classic-bugs/p-adding-to-target-collection-takes-minutes-on...

[DaMoroshka!]

My topic dealing with a very important bug in current Lightroom Classic 13.5.1 on Mac has been locked again, because I did not accept the moderators' modification of the title of the topic! 

https://community.adobe.com/t5/lightroom-classic-discussions/two-minutes-for-item-to-appear-in-colle...

Original title was descriptive of the issue "Lightroom 13.5.1 has huge lags in multiple operations with cloud sync running" but moderators changed it to "Collections take 2 minutes to appear in list" which was misleading and not descriptive of the main issue. 

After I have pointed out to them that my issue is not about "collections taking 2 minutes to appear in list", but about lags in various vital operations, like new collection creation, adding pics to collections, exporting pics, applying AI mask presets, updating previews for edited pics in Loop vs Develop modules to name a few - ALL of them direclty connected to whether the cloud sync is enabled and running or not, 

they locked the topic so that nobody can add any information. Many people chimed in before that they have similar issues, but the moderator power wielding and pride seems to be above job responsibilities for them! 

I am looking for a person at Adobe who would deal with this situation and punish the selfish moderators.

As the team seems to be working on your issue with your log, which has been confirmed by Rikk, it does not help to open a new thread for the same issue.

Do you by any chance have sync and automatic xmp writes turned on. There are some reports of a bug that leads to extreme slowdowns if both of these are on even when doing simple stuff such as adding to a collection. Try turning off automatic xmp writes and pausing sync. 

[wroublin]

I'm going trough thepreferences for a second time, but there's no automatic xmp writes setting. Where can i turn it off?

[Jao vdL]

It's in catalog settings

[wroublin]

Okay, so my automaticxmp write setting is and was not turned on. Also, turning off sync for collection did little to no effect, as well as pausing sync. Still it takes more than a minute to add a photo to target collection 😞

[wroublin]

apparently it works better now, when I paused the sync activity and turned off the target catalogue sync, the changes weren't immediate though, It just got better after couple minutes.

[Rikk Flohr: Photography]

I was able to replicate this with the following instructions: 

1. Select a PV2 Image
2. Create a new Collection, make it sync, include the currently selected image, and set a target collection in the dialog
3. Attempt to update the image to PV6
4. The image does not update to PV6 until several minutes have passed or will update immediately if you pause syncing.

Hey Rikk,

Despite the fact that  you've now been forced to accept  that my thread which you worked so hard to dumb down and downgrade and silence is indeed indicative of an issue,  you are still continuing with your old tricks!

You merged it with the bug report which only deals with specific "Lag in new target collection creation"  and was filed September 15. My thread was much more broad and descriptive, it reflected the nature of the issue more fully, since it is not limited to only Collections, and it was initially posted in early July!

May I observe here that your Process Version update lag (which you were able to reproduce, halliluja!)  is just one of the dozen possible lags happening as a result of this bug. Similarly,  updating the Loop preview can lag (after editing in Develop module, switch back to Loop and the preview is not updated to reflect edits), the apply auto tone corrections command lags, export image lags, create new collection lags, add image to collection, apply AI masked presets, and several others. What is interesting, is the fact that other commands, like making edits with sliders, etc - all work fine.

So the lags are present only within a specific set of commands (that somehow got intertwined with the background sync processor thread which is only allowed a very limited CPU resource). Please update the title and issue descriptoin to reflect all the above,  if you are indeed interested in helping the community to fix the issue, and not only in exercising you moderation powers by locking, merging and editing titles in a way that makes it very hard to find the issue or understand its nature (senior management is now watching you, so tread carefully)!

[DaMoroshka!]

The bug is still rampant and makes my Lightroom impossible to use, as of 21 Septermber 2024! I have also noticed that if the sync queue is above 10 thousand images, the lags become atrocious! 

[GoemonX]

Same here, Lightroom Classic is still unusable. 

However, right now I've noticed that as soon as the synchronization starts, RAM fills slowly up.

With sync deactivated Lightroom uses between 2GB and 5GB of the 32GB RAM of my Mac and works as intended.

When I start the synchronization Lightroom tries to reserve more and more memory. 

After an hour it still has not uploaded any photos, but tries to use 85GB RAM....which just does not work.

Lightroom Classic becomes unusable at this point.

Strangely enough, this continues even if I pause sync again.

[DaMoroshka!]

My RAM usage is "kind of" withing normal - 11-12Gb after several hours syncing

[dabour]

I turned my syncing on the other day - after the sync finished, I was maxed
out on ram with 32 Gb... :-(. Once I turned sync off and restarted Lr, it
was fine.

Same issues for me. Catalog with 500k images, 400k synchronized. All was working fine before sync mechanism changed (on another platform?) and the conversion on my catalog. I think issues are related to the structure of the catalog (bug in the database?) . it work with a new catalog but i need several days/weeks to import old one. And I lost too much information with sync. collections . This is a nightmare ..

[DaMoroshka!]

Is your problem only with "creaing new target collections" or with multiple lags in different parts and operations withing Lightroom Classic? If the latter please complain about moderators of this thread who are stubbornly changing the title of my bug report to dumb it down and downlplay the issue!

[wroublin]

Actually most of LR classic operations are lagging. Back in time it was all
light speed fast, now everything takes ages, but the worst for me is
working in collections, as I do not even see the result of my actions and
doing it twice makes me loose photos I selected for my workflow.

[DaMoroshka!]

I filed this as a bug way back in July when the new release (13.3 I think) with revamped sync engine was released and all this trouble started. My post contained detailed descriptions, and I have provided all diagnostic logs to the Adobe teams.

Despite all that,  my thread was immediately moved from bugs to Discussions and the title of the topic was changed from "Multiple mission critical operations lag with cloud sync working" to "Collections take 2 minutes to appear in list". I protested and tried to edit the title back which only lead to the thread being locked by some obnoxious megalomaniac moderator. After I reported this counter productive behavior of moderators to Adobe customer care my thread was merged with a bug report that was filed very recently in September and under very non-descriptive title  "Target collections take time to appear" which is just one particular instance of this bug, but by far not the whole story.

There is some hope that this issue will be finally resolved and we will have a normal bug thread with a proper title as I was told today that my complaint was escalated to higher management and they are dealing with it right now.

Greetings all, 

A new update for Adobe Photography Products has been released.  The October (MAX) update contains an update for this issue. 

If you do not see the update in your Creative Cloud Application, you can refresh it by hitting [Ctrl/Cmd]+[Alt/Opt]+[ R ].

Note: It may take up to 24 hours for your update to be available in your Creative Cloud app.

Thank you for being so patient.

[warm_sharpness5ED8]

I've installed the October update and still have the slow issues.  I'm currently trying to sync around 2000 photos and its doing about 10 in an hour.  I can't do anything else I tried transferring images to external hard disk and its transferred 81 and froze, won't do anymore.  I'm fed up of this now, I'm trying to run a business and I can't get my clients photos edited on time, its ridiculous, we should get a refund on the subscription.  LRc is only using half of my CPU cores and only about 30% on each core.

[DdeGannes]

@warm_sharpness5ED8 @Prior to your upgrade to LrC 14.0 was the syncing of images to Adobe Creative Cloud free of sync errors?

[warm_sharpness5ED8]

If you mean did the cloud icon have a green tick, yes it did, if you mean did I have the same issues prior to 14, then yes I had exactly the same issues.  Another example is, picking/rejecting images takes minutes to show the appropriate icon on the image.
