Hi Folks,
I’ve been trying to get some reasonable performance out of a Mac Mini M1 with 16GB RAM and a Crusial X8 1TB SSD as a temp drive for two days now, but I’m still over 3 hours per plot. Now I’ve added a Samsung MU-PA1T0B/EU Portable SSD T5 1 TB USB 3.1 as a temp 2 drive but I’m still over 3 hours.
I’m a bit surprised because everyone raves about the high speed of the M1 Mac. What am I doing wrong?

Does anyone see where the bottleneck is and what I can do about it?
