So nobody has figured out how to generate the plots quicker yet? I think I have a solution that should generate them anywhere from 100-500 times faster. If I get it up and running (give me half a day) I'll let you know

I assume this is a gpu solution? If so, glad to see someone else doing it so I don't have to

Actually no, nothing as involved as that. I started looking at re-writing it in C++ (which would be more efficient for sure) then it dawned on me that this can be done in a much simpler way, though probably not a way suitable for everyone. The creation of the plots requires a lot of computing power, but only needs to be done once. So my not-so-pretty solution is simply to distribute the plot creation out to a farm

If I can get it working, I think I should be able to achieve upwards of 1TB an hour, maybe 10x this if I have my calculations correct. In theory I could produce plots for other people, but creation speed would be limited by their internet connection so not really practical

I thought about that once also, but the networking speed was a deal killer, since there really isn't any mining benefit over having each machine generate its own set of plots, then just grabbing all the hdds.
You might not be able plot for other people online like that, but you could sell them pre-plotted hdds.(wonder if there'd actually be any takers on that one.)
