Optimal plotting on Mac mini?


I was wondering if anyone could please help me to figure out the optimal plotting for my machine:

  • Mac mini 2018 with 3.2 GHz 6-Core i7, 32 GB Ram
  • 2x 960 GB NVMe m.2 connected via USB-C

One plot takes around 6h when plotting a single one. First stage is done after around 2.5h and 2nd stage takes another 1h (3.5h in total after 2 stages).

I was wondering what I would need to do in the GUI to optimize plotting per day.

Thank you!!
