Huge difference in plot times between the first (when jobs were still ramping up) to the later ones after all 6 jobs are cranking. The math says that if I decrease parallel jobs from 6 to 5, the individual plot times must decrease from ~34500 to ~28900 to maintain overall throughput. I suppose I can try it by killing off a job… Hmm…
