There’s not a lot that can be said. The general advise seems to be: start small, record your timings and adapt.
Start slow with one plot, record timing, then try 2 in parallel, record timings, figure out where your bottle necks are. That’s how I started, it’s a lot of hands-on trying out for the first few days! As I said in another thread, don’t try to go too fast at first: GUI stop working in plotting - #3 by cultiv
You only have 2 plotting disks, so start with 2 plots (4 threads each), record timings, then do 2 in parallel (4 threads each), record timings, then 3 in parallel (4 threads each), record timings, then 4 in parallel (4 threads each), record timings, then your CPU might run out of cores, so then you might need to start staggering them.
@cultiv you have the very best advice on this and an excellent bedside manner
We should have a FAQ on this… “How do I start I don’t even know what to do”… it feels like people jump in and immediately start 50 parallel plots because… people… when they should just do ONE plot, time it, and test… sigh.
Dip your toe in the water before diving in, people!!
