Issue With Editing a Set of Photos In Lightroom

[SnowAngel_Photo]

I'm having an issue with editing a set of photos in Lightroom. It takes forever for the photos in the set to fully display. When the photos finally display, it's slow to do  edits. In a set of over 100 photos, I've only been able to edit about two because everything is super super slow (this is after days of trying). I don't believe it's a matter of the photos being too large or any of the other tricks needed to make Lightroom faster (but not completely sure). It's only a particular set of photos that I'm having an issue with. I can edit other sets of photos normally.

Any ideas of what the issue could be?

Some participants in this forum have found that their anti-virus software has caused similar problems. Most anti-virus software provides a way to exclude programs and files from checking.

Next to the important hint from KR Seals: What is the exact version (numbers, not 'latest') of your LR?

What is your OS?

Please verify if it helps to turn off the GPU if it's active now: Adobe Lightroom GPU Troubleshooting and FAQ

Hello!

Thank you for your responses!

What steps must be taken to determine whether or not the anti-virus software is the issue?

Also, I have LR 5.7 and my OS is Windows 10 Home. I couldn't find the option to turn off the GPU after searching under Edit>Preferences>General per the recommendation from the website.

Can I recommend the articles by Victoria Bampton that address "Performance"

Start at-

https://www.lightroomqueen.com/lightroom-performance-complete-series-optimizing-lightrooms-speed/

I am unsure, but I don't think the CPU switch was introduced to Lr until v6.

And my list of topics to consider-

Update drivers for graphics card  from the card manufacturer.

Update drivers for wacom tablets.

Dis-connect mobile phones from usb

Folder permissions must allow “read & write” on working folders

Do not use external hard-drives through a hub. Plug directly to a motherboard usb socket.

Turn off face recognition.

Turn off mobile sync (set to "Pause") while working in develop module.

Limit the use of the Spot Removal Brush. (Extensive 'spotting' is best done with Photoshop)

Preferences options-

Delete the preferences file (or reset when starting Lightroom   shft+opt/alt )

Uncheck “use graphic processor”

Turn off ‘automatically write to .xmp’

Increase cache size.

Ensure sufficient space (20%?) on the catalog working hard-drive.

Last resort: Use Adobe CC Cleaner Tool to Un-install all adobe programs then re-install- 

And the Adobe link- Optimize Lightroom performance

What steps must be taken to determine whether or not the anti-virus software is the issue?

Turn the Real-time scanner of your antivirus solution off - all AV solutions I know allow this from a symbol in the system tray - and then try again to work in LR. Make sure to close your email program and do not browse the web while the AV is turned off ... just to be safe.

Also, I have LR 5.7 and my OS is Windows 10 Home. I couldn't find the option to turn off the GPU after searching under Edit>Preferences>General per the recommendation from the website.

As wobertc already said, the GPU acceleration has been introduced with LR6 and therefore this can't be your issue.

Only affecting a certain set of photos with no differences from other photos - I'd suspect something like file corruption in one of them. Maybe try leaving those images as is and reimporting copies, see if the problem persists with the new ones.

[SnowAngel_Photo]

Still no luck, but thank you all for your suggestions. I appreciate each of you for taking the time to help.

Looking again at your question-

What do you mean by a "Set of Photos"?  Are you referring to photos all in one folder, or a Collection, or Smart Collection?

Are the originals stored in an unusual location, a different hard-drive, etc?

And have you considered or tried some of the topics in post#4?

We hope you do find the 'luck' and get things working better.
