Lightroom Classic faster on Intel MacBook Pro, Slow on Windows 10 PC Workstation

Question

Hello,
 
I have a 2015 Macbook pro, nothing fancy. Lightroom works like a dream on it. I also operate on a HP Z8 Workstation. It's no exaggeration to say that lighroom slows down my PC to a halt. When importing photos especially, it is sitting and waiting upwards of 30 minutes for the program to be usable, and even then it's spotty. I have zero clue as to why it would work fine on a laptop and be unusable on what is supposed to be a workstation designed for this type of work.
 
Here are some PC details:
Processor Intel(R) Xeon(R) Gold 5120 CPU @ 2.20GHz 2.19 GHz (2 processors)Installed RAM 32.0 GB (31.7 GB usable)Device ID C4A70D15-64B6-4792-A81F-A354759CB940Product ID 00391-70000-00000-AA669System type 64-bit operating system, x64-based processorPen and touch No pen or touch input is available for this display

Any help is appreciated

You're using the 'Add' import option, which suggests that you have already placed the photos in the final location (i.e disk and folder hierarchy). Is this correct? If not, then please describe your import procedure (e.g. are the photos imported from a card reader, direct from camera, etc). Some additional information relating to the imports would also be useful:

1. How many photos are you importing

2. What size (i.e. MB not MP) are the photos?

3. How much remaining space do you have on your 'C' drive?

4. Which drive are your photos stored and has it got enough spare space to store these photos?

5. Do you have a virus checker and is it continually monitoring your disks?

I believe I figured out the issue. I changed the import settings to 'Minimal' under Preview settings wehen importing. Seemed to do the trick

I'll help you figure this out. Thanks for sharing the info about the machine. I'll need the Lightroom Classic > Help > System info. Does it slow down after a specific set of steps? Is there a noticeable pattern to this behavior?

Besides Lightroom getting slow, does the RAM usage peak, abnormal temps, CPU usage, and unexpected read/write operations?

To begin troubleshooting, test some variables like:

Unplug any external peripherals & use wired input devices.
Unplug external drives.
Go to Lightroom > Preferences > Performance > Use Graphics Processor > Set it off if it is on Custom or Auto. If this shows you any differences, please check this article to troubleshoot further: https://helpx.adobe.com/lightroom-classic/kb/troubleshoot-gpu.html
Reset Lightroom Classic following the second (manual) method from this article: https://helpx.adobe.com/lightroom-classic/help/setting-preferences-lightroom.html

Let me know how it goes. Thanks!
