Strange Lightroom Classic "performance issue"

For quite some time, I have been trying to improve the LR Classic performance (e.g., responsiveness to adjustments) after I upgraded to two 4K monitors. The symptom is sluggish response to adjustments and frequent multiple beach balls. It is bad to a stage that I don't use the 2nd monitor when I do photo editing. I have been using my Sony A9's RAW files that have 24MP images.

I thought my MP 6,1 with 10-cores and 64GB RAM was aging and needed upgrade. Then last night I saw FroKnowsPhoto's YouTube video and decided to download his A7R4's RAW files (61MP). To my big surprise, these 61MP RAW files work fine with my MP6,1! With two 4K monitors, it just works smoothly just like how I remembered.

How do I further debug my configuration? These A7R4 RAW files are in DNG format and my A7 RAW files are in ARW format. That is the only difference I can find.
