P: "Synchronize Settings" very slow, using 10% CPU

[naestyoh]

I have a 300-image (NEF) folder where I highlighted all images, turned on Auto Sync, then adjusted the sharpness, noise and applied lens corrections. LR Classic has taken about 15 minutes to process 50% of them. When inspecting the CPU, it's only being 10% utilized (out of 1600%)... basically the system is idle. -- 8700K@5GHz with 64GB 3GHz DDR4 ram.

Lightroom Classic 9.0 was released earlier today and contained a fix for this issue. Please give it a try and confirm it is working for you after updating. Thanks for your patience.

Just updated, I think its actually slower. 

Edit:

So the problem isnt resolved at all but I have a new one for you all, cancelled the sync (which actually prevents me from doing anything more in lightroom.. so close the software). Lightroom has been closed for 10 minutes. The sync options window pops up for me out of nowhere. Fantastic. This is no longer professional software. I'm sure its fine with the latest Macbook "Pro" at the Starbucks crowd but I'm done.

Confirmed that it's stupid fast now. As fast as any other adjustment auto-sync. Thanks!

Could you also move the photo info overlay to not be an overlay, rather, in a strip above the image that can be turned on or off -- no cycle. I want to see both views combined in a strip. (add MP next to file res). I'd buy you a flight at Schilling... .

Things seem to have improved, for me.

Sadly the new update has now broken a key feature of the LRTimelapse plugin/integration, which is bad news for timelapse photographers across the world. I'm sure Gunther the dev behind LRTimelapse will start (or already has started) a new thread regarding that. Thank you though, for the update and for fixing the issue (haven't tested myself FYI). Matt (just got back from MAX, what a trip!)

I just retested the recipe I posted above in LR 9.0, and now Sync and Auto Sync of Enable Profile Corrections to 400 photos both go fast, about 2 seconds.

I'm actually trying here... a folder of only 6 selects (outputted from Capture One).. wanted to do some crop options, B&W options.. whatever... Crop tool is completely non responsive.. I wish I was like everyone else and have my problem solved with an update, but it never is. The worst thing is, this computer is purely a work machine.. this is all i do on it.. i built it for this purpose.. 
It could definitely be something wrong with my system, however... Capture One works 100% and is super responsive...

Not related to the solved thread where originally posted. Forking to new thread

Please reference the new conversation here: Lightroom Classic Crop Tool Non-responsive

I want to chime in to say that sync settings is still broken for me.  I'm on 9.0 on a 8700k, 64GB and GTX 2060 PC.  On import I have adjustments that apply to exposure, color, detail and lens correction.  I will make adjustments to an image then select a handful of them and ctl, shift, S sync them with just exposure and white balance syncing it takes about 2s per image during which I cannot do anything else.  Editing an event with thousands of images has become painfully slow, this is a huge bug and has not been solved.

Your issue may be different from the one that was marked "solved" in this thread. The original issue involved syncing lens corrections, while you're syncing just exposure and white balance.

I recommend you post a new topic. To make it more likely that Adobe will be able to reproduce the problem:

- Include the first ten lines from Help > System Info.

- Include a screenshot of the Synchronize Settings window.  

- Provide the exact camera model of the photos triggering the issue.

- Upload the preset that's being applied on import to Dropbox or similar and post the sharing link here.

same. i used to sync setting in seconds, and now im sitting here with a 1600 image timelapse for over an hour. 

[FeedbackCommunityMember]

not working here. syncing settings (NOT AUTO SYNC) takes too long. on my imac from 2014 with an old version of lightroom my syncs happen instantaneously. what did you guys do to LR?!?!

[FeedbackCommunityMember]

   Have you found a solution to this problem? I noticed that the sync speed drops only if you sync the white balance. Someone said that this is due to a cloud update, but there is no network load in the Manager. I didn't find any settings where to disable syncing with the cloud to check it.

For everyone is trying to deal with this. Deactivate Masking option in your sync setting and should be much faster...
