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

@Rikk Flohr: Photography After you have multiple times downgraded my thread from bugs to discussions, then locked it multiple times because your "forum decorum" was rhyming in your head and you thought it proper to punish me for editing MY OWN THREAD TITLE, then after finally you've successfully diluted it by MERGING with a bug thread posted much later, with misleading description and dealing with ONE PARTICULAR INSTANCE of the issue (lag in creating collections), but nowhere touching on the core of the problem (poorly coded sync engine) and not touching on a dozen other even more serious instances of that same bug (lags in other various vital workflow operations),

after all that you are saying "nobody is preventing you from filing"? You are a funny decorum rhymer! I hope Adobe soon realizes that employees like you who care more about your own decorum and display of your moderation powers are a detriment to company success. You are obstructing investigation of a very serious bug affecting perhaps thousands of users! I hope Adobe management will rhyme it up with you 😉

@DaMoroshka! 
"Once again a plea to moderators - please allow me to create a proper bug thread with adequate issues description."

No one is stopping you from creating a proper thread describing the issues you are facing as long as you do so within the best practices, Community guidelines, and proper, respectful forum decorum. (I love that the last one rhymes)

Some recommendations: 

1. Post in Discussions (Read this: https://community.adobe.com/t5/lightroom-ecosystem-cloud-based-discussions/p-do-i-post-in-discussions-or-bugs/td-p/13691888)
2.  Use a descriptive and precise subject line (Read this: https://community.adobe.com/t5/lightroom-classic-discussions/p-fine-tune-the-subject-line-of-your-adobe-community-forum-post-for-better-results/td-p/13476026)
3.  Do not combine issues.  Regardless of whether you believe they are related or not, post individual problems as unique threads. This avoids your threads being combined with a mish-mash of others. 
4.  Use Precise terms.  Lag, sluggish, and other descriptive but imprecise terms tell post readers nothing.  Describe specific operations and use specific time increments. Example: "It takes 20 seconds for the Export dialog to open" - not "this program lags on everything."
   4. Do not alter the Moderator's text. It is there to accurately and effectively improve your post's visibility and, ultimately, provide a quicker solution. Altering a moderator's text may result in your thread being locked. 

Realize that the Adobe Staff, Legends, Community Experts, and other members are here to help you, and your results will improve by following best practices. 

I look forward to your new posts. 

Rikk reported: "The October (MAX) update contains an update for this issue" and also the bug seems to have changed to "fixed" status. 

1/ Bug has not been fixed. 

2/ The real issue is not limited to "Creating Target Collections..." - moderators won't let me file this bug with proper description - it deals with lags in MULTIPLE Lightroom operations with cloud sync enabled, including but not limited to "auto-tone", "update to current process version", "apply Portrait AI preset" etc. I still see ALL OF THOSE LAGS in 14.0 OCTOBER MAX update (weirdly, export command seems to be working normal now - while before it used to be in the "lags" category - so there may be a bit of an improvement in 14.0)

Once again a plea to moderators - please allow me to create a proper bug thread with adequate issues description. I did it as far back as July 2024, and ever since my thread has been - RELEGATED to discussions, LOCKED, and MERGED with other less adequately described bug issues. 

We need a proper thread for this LAGs bug - it has not been fixed in 14.0! 

Exactly same issues for me. I will update with Lrc 14 but I don't hope a lot.  I just noticed that if I suspend synchronization and kill several times the process "Adobe Content Synchronizer", I can retrieve some performances.

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.

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

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.

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.

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!
