I just started to replot all my disk. My plotter and farmer are the same I have all in one.
Each plot take arround 5 or 6 min to be created but the problem is the plot transfer to the final destination take arround 20 min for each plot to be done, for example the plotter give me some messages like " Waitinf for 901112 MiB available space on: /media/xxxx" or “All destinations are busy or full. waiting…” in 24h I made only 50 plots.
What I missing? I don’t have any clue about how used Plot_sink because I don’t have any network and I don’t know how to build it exactly, also I read something about SSD Buffering but I’m not sure how to configure it. I have 3 nvme high speed available 2tb each and an Asus Hyper M.2 X16 card, Could be enough to get a good configuration.
RTX 4070 ti 12G
3 x Samsung 990 pro 2tb
1 x Samsung 980 pro 1tb
Asus Hyper M.2 X16 card
Could you please in your experience recommend me what to do to improve my performance? Thanks in advance!!!
i am glad to hear that the times are ok. if you feel like it, you can check a few things to see if everything is really optimal.
sometimes I have the problem that after a reboot the RAM runs with low speed (only 2133 MHz instead of 3333 MHz).
then the plot times are about 20-30 seconds longer
to check this: sudo dmidecode -t memory
on some mainboards not all NVME slots are connected with x4 sometimes some are only connected with x1, just check the manual to make sure the right slot is used
if your plot times get worse after some time (30-60 minutes), a regular trim of -t /dev/TEMP is necessary
and last but not least a good cooling of the NVMEs is important because they are under permanent load normally from 50°C on they clock down and that costs a lot of time.
to check this sudo smartctl -a /dev/"YourNVME"
There are GPU VRAM and CPU RAM requirements in the link. The “harvester power thing” is that a CPU is not as efficient as a GPU in finishing the ‘compressed’ plots during farming. GPUs are not general purpose computing engines, but what they can do, they do efficiently, with less power than the same thing done on a CPU (if even possible on a CPU).
So with your CPU it can do the work, up to a point, but not power efficiently, on a certain number of requests to finish plots. There are formula and there is also a plot check tool to tell you how much can be farmed, but generally, almost any GPU is going to be better than any CPU.
For more detail search and/or visit the relevant Discords, etc.
GPUs can usually do what CPU do, but more efficiently because of their architecture.
Maybe for smaller farms, CPU can still be better, but the logic is that GPUs (and maybe in the future of Chia even FPGA/Asics) should always be faster and more efficient, unless the design doesn’t allow for parallelization.
