So, just finished the first plot. Here is the set-up:
- intel i5 6600K (stock settings)
- Asus Z170-Pro
- 8GB DDR4 2666MHz Corsair Vengeance LED Ram
- Crucial M500 240GB SATA SSD (Temp 1) (R/W ~500MB/s)
- Sandisk SDSSDH 240GB SATA SSD (Temp 2) (R/W ~ 550MB/s)
- Seagate Firecuda 1TB Hybrid SATA HDD (Operating System)
- Ubuntu 20.04 (Kernel 5.8)
Literally all the hardware I had left lying around to set-up this experiment lol. But I think it is comparable to what you have.
Here is the log

So it took just shy of 6 hrs to complete. Looks like it ran significantly faster than yours. But still painstakingly slow compared to a modern system. (My main PC right next to it finished 11 plots in the time it took for the server to complete 1 lol)
Observations:
First of all it, surprisingly, it didn’t hammer on the CPU. It was utilising around 25-40% the entire time. Similarly, the ram usage was very low too. It looked like Madmax was hitting the drives at full speed about 50% of the time. My guess is that is a bottleneck on the SSD side.
For illustration purposes
I shall swap in my MP600 Pro into it. It’ll be limited by PCIe 3.0 speeds, but it’ll help to narrow down where the hold up in the system is. But at least, you have the above log to compare your system against.
Will get back to you when I have more stats for you.
