I bought a high spec PC for Chia plotting yesterday and looking for feedback on what I should upgrade for faster plotting. The relevant specs are : Intel i9 9900kf, 64GB RAM, Samsung 970 EVO PLUS 2TB, Ubuntu Linux.
I’m using 2 threads and 6.5GB RAM per plot. Bizarrely, only around 18GB of RAM in total is being used (but 100% of 1GB swap is being used - not sure why it is paging to swap?)
I started running 7 plots about 6 hours ago with a 20 minute stagger and they are, on average, now around 55% complete. Extrapolated out that would amount to 1.6TB / day, which seems very low for such a powerful machine given that you can get 1.2 TB / day on a Mac Mini.
My questions are:
-
Is that reasonable performance for this machine? Am I using reasonable settings?
-
What is likely to be the best upgrade to alleviate bottlenecks so I can plot faster?
