I wonder if the plot would look similar if you disabled hyperthreading but kept the same number of workers.

  Ah I _think_ I ran this on a MacBook that as far as I know has 8 real cores… But I since found that 4 are “efficiency” cores, so that could be the reason for the poor scaling(?)

    Seems plausible to me. The efficiency cores seem to be clocked quite a bit lower.
