How long should phase one be on 3995 threadripper?

Running in parallel while using 2TB NVME, 4 threads and the standard 3890 in RAM I am averaging around 133 minutes (8035 seconds)

Does this seem too long or right on the money?

How many in parallel? How many in phase 1 at a time?

15 in parallel with a 60 minute stagger.

Its a 4 TB NVME drive.
