Copying while plotting, slows down total seconds for plotting #856

Open chinabala opened 3 years ago

chinabala commented 3 years ago

I've noticed that my single plot time's 1600s, but when continuous plotting will increases to 1800s-1900s per plot. (I understand to use -w instead, but..)

Wondering would it be the CPU problem or SSD bandwidth or something...

And, what if distribute copying to HDD through out whole plotting phases evenly. Would it help?

the -w feature was created to address that issue.

Remember that you are (generally) targeting total throughput, not a small number of seconds somewhere in the log. I generally have embarrassingly slow plot times but have more than one going at a time to get peak throughput. This applied to chiapos and at least for myself and various others to madMAx as well. I have found that even with --rmulti2 I can't keep my system busy outside of phase 1 so I run a phase1 stagger via plotman and end up with three'ish madMAx processes going at once.

So, keep an eye on your daily throughput instead of the plot duration.
