here’s my hp z440 workstation setup:
CPU: intel xeon e5-2680 v3 (12 core, 24 threads)
RAM: 64gb DDR4
SSD: sata ssd 120gb to run ubuntu 20.04 OS
NVME1: Crucial P2 2TB PCIe M.2 2280SS SSD (connected using pcie 3.0 adaptor 1)
NVME2: Crucial P2 1TB PCIe M.2 2280SS SSD (connected using pcie 3.0 adaptor 2)
GPU: NVIDIA NVS 300 for video output
HDD: 4x seagate 8t external HDD (actually only 2 of them connected)
All i did is install chia blockchain (it should be the new 1.1.7, but on help i see Chia Blockchain 0.0), mounted SSDs and HDDs increased swap to 16gb and changed swappiness to 10 (swap seemed it was the problem on my first 11x parallel test)
my first solo plot was 20gb ram, 15 threads, 128 and it took around 9 hrs to finish, i then tried to add 3 more parallel plots using 4gb ram, 4 threads, 128, everything seemed fine but the first got stuck at 31% no errors were shown on the log file, it was just freezed and after a few hours i decided to shut them down.
i also tried to remove completely the swap since my 64gb ram is more than enough and i tought that was the reason of the slow plotting speed but it didnt help.
i tried quitting plots, deleting all the nvme files and replot again but it struggles to reach 1% too,
i’m running 4x parallel plots 4gb ram, 3threads, 128, temp on ssd1 and saved on hdd1 + 3x parallel plots 4gb ram, 3 threads, 128, temp on ssd2 and saved on hdd2 and after 2hours they’re still at 4%.
I’m new to chia farming and ubuntu as well, i decided to run it for better performance, but i cant stand what is making my speed so slow without any shown error.
i tried running ram performance test and it was alright, maybe i’m doin something wrong with settings or plotting itself?
i’m pretty desperate, every help and suggestion will be very much appreciated
