I am going to see if this changes much with the more memory.
As well as trying Bobzeq's guidance. Right now I have 3 swapfiles but have 6 physical cores. Bobzeq, is that 1 swap for each physical core or logical core?

I got around to optimizing today, I might post graphs of the results if I get time...
Tested swap files to Ramdisk from 2 to 16
Tested swap files to SSD from 2 to 16
Tested Ramdisk from 2GB to 16GB
This was the best combination and corresponding Benchmark Totals:
Old Computer (1 swap file to SSD) = 2,108 (i5 4 core 4 thread, 8GB Ram, 1TB spinner HD)
New Computer, PI as installed (1 swap file to SSD) = 8,619 (8 core Ryzen7v2 16 threads, 24GB Ram, 256GB system drive, 1TB spinner HD)
New Computer, Optimized = 12,589
Optimization = 12GB Ramdisk, 8 swap files to Ramdisk, 8 swap files to SSD
Testing for optimization is time well spent, gave me ~ 50% increase in performance.
Increase in Benchmark Total Old to New computers = 12589/2108 ~ 6x
