Can anybody help me out?
I've been trying to use the Mad max plotter on my 64 core Rome ES, but it's really slow.
2 x 300 gb 10k SAS drives = 7.5 hour plots with 128 threads (used to be ~15 hours on the GUI/powershell but on each drive, so no improvement really)
Sloth Tech TV churned out a plot with 2 x 300 gb 10k SAS drives in 73 mins on DDR3 memory, I'm nowhere near that.
I even tried to make a RAMDisk with ImDisk (when I made a 110 GiB drive, the plots crashed. I have 128 gb total, so 110 GiB tmp 2 drive, an NVMe ssd (Corsair Force MP600 1TB, yes, it's not great, but it's not supposed to be slowing me down this much). I tried giving a few more gigs to the RAMDisk and setting less threads, but it was still TOO slow.
The first thing that I immediately notice is how slow it takes to create Table 1. A threadripper in RAMDisk took 6 seconds to make Table 1. When I tried it with the RAMDisk overnight, it was like 140 seconds, but it crashed. On SAS drives it takes like ~300 seconds, on HDD's it takes 400+ secs.
Here is my current attempt, on 2 x 300gb 10k SAS drives, but it's still way slower than it should be, and I'm running out of ideas:

What I have already tried:
Another interesting thing that I noticed is that when I launch the plotter with just 1 thread on the 2S cpu, the table gets made in ~130 seconds, but when I add more threads, it actually happens slower. Btw, in task manager is shows 2 sockets instead of 1, on Win 10 Pro it showed one as it should, but the times were the same. So when I set 128 threads, I see only half of them getting used up. But it's still way slower than it should be.
So there really must be a problem with my EPYC platform.
My setup:
ASUS KRPA-U16 version 0302
2s1404e2vjug5 64-core CPU
M393A2K43DB3-CWE x 8 sticks
Windows Server 2019 version 1809 build 17763
HP Smart array p410 1gb for the SAS drives, so yeah it might be shit BUT what's up with the RAMDisk tmp2 + NVMe temp 1? It's still not supposed to be that slow.
The BIOS is pretty much stock.
My only wild guess is that maybe there's a bug with 8 channels or something.
$20 PayPal to the first who figures out the culprit.
Thanks in advance.

What I have already tried:
- Different versions of the windows Chia plotter
- Different OS's (right now on Windows 2019 Server, tried Win 10 Pro, and Ubuntu.)
On Ubuntu I couldn't get the overclock tool to work, and at default clocks it was still really slow on phase 1 (same times as Windows) - 256 buckets seems to be faster than 128, but not a drastic difference
