Lightroom classic is running so slow it is almost unusable

I have been using Lightroom since version 1.0. I am up to date with my updates on the current classic CC. It has been running so slow for the last several months it is bordering on totally unusable. When I open it takes minutes to load. Every click on the import process, from import, to selecting the drive, to selecting the folder (both for cards and already-uploaded on RAID on USB-C connection), takes 3-6 minutes. I often get the whited out scren and Lightroom is not responding message before it comes back again.

I am running it on a I7-3770k processor, Nvidia GXO1060,, 32GB RAM, with the catalog on its own SSD. I start the new year with new catalogs for my commercial and news photography, so the catalog have hardly any photos in them. The photos are from a D4 and D810. I regularly optimize the catalog. I do not have an enormous number of presents.. I've done nearly every step on the optimization web page. Help????

Hi there,

We are sorry about the experience with Lightroom Classic. Would you mind sharing the version of Windows you are using?

Would you mind checking the below mentioned details and performing the steps to check if it helps?

Go to Preferences > Performance and increase the Camera Raw Cache size to 10.0GB or more.
On the same tab, check the option to Use Smart Previews instead of Original for image editing and uncheck the option to Generate Previews in Parallel.
On the Performance tab itself, select off from the drop down for Use Graphic Processor
Go to the General tab and check the box to Replace Embedded previews by standard previews during idle time.

Once you have made the above-mentioned changes, quit and relaunch Lightroom Classic prior to testing the application.

Regards,

Nikunj

Do you have a Logitech mouse or keyboard, and if so, have you installed Logitech Options?

This program installs a Lightroom plugin, which is known to cause Lightroom to take a long time to load, and possibly also other problems.

The plugin can be disabled by going to File > Plugin manager.

I do indeed have a Logitech mouse and the software, but no plugin is appearing in the plugin manager. Do you think it could be an issue with On1 plugins? Or Smugmug?

This has made things better for me. Thanks! Mine was running so slow despite my laptop being an absolute beast.
