Develop module Lightroom has come to a Crawl

Lightroom Version Number

13.5.

Operating System

1. Windows 11

Hi

I am having a lot of trouble with LR running so slow that it is sometimes almost unusable. I also use Camera Raw in Photoshop, and that runs like a charm. I thought I would get the same performance from both, but that is not the case. While importing and exporting, I can not do any other work. Here are my specs
Thanks in advance

Have you checked what might be syncing? The sync process has changes in 13.3 and maybe in more recent updates. This can caus the Sync proces to consume lots of resources. This is especially true if you have deleted your sync data.

 

[degallery]

I double-checked, and the sync is turned off.

Thanks

We know that your GPU is an NVIDIA GeForce GTX 1660 SUPER. This is now 5 years old. It will struggle with any of the increasing AI features of LrC. It doesn't explain the general sluggishness, nor does it explain why it's only LrC and not Ps that has this problem. However, we don't know your CPU except that it's 2.4GHz.

 

[degallery]

After doing some more research, I came across a thread that said to turn off indexing on my drives and put in an exception in my antivirus. It has seemed to speed things up a bit. There is not much lag between moving images and applying correction to multiple images at once.

I am running an i7

I have (or had) a fairly high spec machine.... which started to crawl when I upgraded my camera from A7R3 to A7RV... could be a co-incidence... but could not prove it.

I got bumps in performance improvement when I removed Lr Catalog and Preview Folders from AntiVirus Scanning and Removing Indexing from all my drives. I got further boosts by upgrading my GPU from a 1650 to RTX4070TI.

I regularly have to recheck the virus and indexing settings, as they get turned on 'by magic' every so often.

I am having a lot of trouble with LR running so slow that it is sometimes almost unusable.

Where are you noticing the slowdown? Is it only when you are doing "While importing and exporting"?

Have you tried checking your settings and/or disabling your "Backup Cleaner"? It seems harmless but the last update was 2018.

 

[degallery]

If I restart my entire system and begin working, culling minor corrections, it's fine. But maybe 10 or 20 minutes in, it starts to drag change photo to photo corrections in both library and develop module lag.

It is never a good idea to include the Catalog file, images or any thing in the Lightroom folder First the virus scanner inserts itself between the app and every file that the app opens. The catalog file is open for write by LrC and the virus also wants to read/check the catalog file for virii. This to me is a recipe for catalog disaster.

Image files and Previews are only accessed by LrC (or should be) these won;t get exposed to a virus if they are transferred from the camera to the computer.

IMO anti malware apps are the biggest reason that Windows users complain for poor performance. Fortunately for MacOS it is not necessary to run any anti Malware apps in the background.

On my Mac, I run Malware bytes perhaps once a month and in over ten years of being a Mac user It has never detected a virus

I'd suggest opening a Task Manager window when you boot. Then look at what programs are taking the resources when it gets slow. In other words, as some have suggested a slow LrC may be a symptom of another program.

 

[Gnits]

You may get a clue ... you may start to hear a lot of disk activity on your drive.... that is a good time to check Task Manager.

That is how I found that antivirus and indexing where having a serious impact on my setup.

Also.... it makes sense.... We often start Lr to import and process images. We will import a batch of images. The bigger the batch the bigger the issue... because as Lr is importing these images and then building the requisite previews... at a time when your machine is under max load copying from card to Disk... the antivirus software kicks in thinking... heck I have a pile of large raw files to check out... at the same time the Windows Index internal app kicks in to do its Indexing trick.

Massive demand for the same computer resources. It may take a while for all queues for the same cpu, gpu, disk i/o to get back to a steady state.

 

[Philippe Coudé du Foresto]

Don't forget the cache file. Increasing it's size, putting it on a very fast non-indexed disk like a SSD and removing it from the antivirus scan might help to improve the LrC performance.
It's location and size can be changed in the Preferences, tab "Performance".
