65K is slower than I would expect with just 3 plots even for sata. That drive is sata, right?
That is at least part of the problem, sata is just slow for plotting. Nvme can be much faster if you get a good drive.
What do you get with just one plot running?
Yes the drive is SATA, my Nvme slot is already used by 250GB SSD, so sad I can’t replace it, got only 1 Nvme slot. The time taken for 1 plot only is 55k secs, 12 threads. Any suggestion?
