Lightroom Classic: "Synchronize Settings" very slow, using 10% CPU

I have a 300-image (NEF) folder where I highlighted all images, turned on Auto Sync, then adjusted the sharpness, noise and applied lens corrections. LR Classic has taken about 15 minutes to process 50% of them. When inspecting the CPU, it's only being 10% utilized (out of 1600%)... basically the system is idle. -- 8700K@5GHz with 64GB 3GHz DDR4 ram.

Sean,

Thanks for the detailed information. 

I am curious if you were to turn off Auto Sync and instead, copy and paste the settings from one image to 299 images if the operation is faster, slower or takes the same amount of time? 

Returning to your original workflow, if you don't apply Lens Corrections is the time affected? If you apply lens corrections but not noise/sharpness?

Here's my CPU utilization when I have a few hundred images selected, AUTO SYNC enabled, and choose to apply lens profile corrections.
