Images slow to load in Develop & Library

[nicholass63509767]

Hi Smart People

I need help.  Lightroom is crippling slow to load the images and I have done everything I can find / think of to speed it up.  In no particular order.

1.  I am running the very latest release, 14.0.1.
2. I am up to date and running the latest from Apple on Sequoia 15.01.1
3. I have 72 GB of memory
4. I have the AMD Radeon Pro 5500 XT 8 GB Graphics Card.
5.  I have a 4 TB external hard drive connected through the Lightening Port and I have 1.4 TB free on that.
6. I disabled all of my plugins.
7. I have optimized my Catalog
8. I only have a 19,000 images in my catalog
9. I have adjusted the Performance to use the Grapics Processor and have a 45 GB cache.  
10. I downsized my preview to below the resolution of my Mac.  
11. I ran system checks on the hard drive and external hard drive and all showed up as great.

Anything else you can recommend?

It come to mind that something has happened to your previews. I could not imagine what.

Select one of your most recent folders (preferably one with plenty of images), then in Library Menu > Previews > Build Standard Size Previews. A screen will pop up asking if you want to do this to all the photos in the folder: Say yes.

Does that help?

LrC should work fine with Standard Previews set to the size equal to your screen resolution.
