There are 4 major phases to plotting. Phase 1 of plotting can utilize multi-threading. Phases 2-3 do not. You can better optimize your plotting by using the -r flag in your command and setting it to greater than 2, e.g,. -r 2. Above 4 threads there are diminishing returns. Many Chia users have determined it's more efficient to plot in parallel, rather than series. You can do this by just having multiple plotting instances open but staggering when they start 30min or more.
