Comment was on wrong thread.
sas too slow you need ramdisk or nvme ssd i use Dual E5-2689 , 384G ram ,128 buckets , total plot time is 2030s

What's your CPU usage ? does it take up all threads?

yes ,use all of 32 threads about 90% at Phase 1

Can you share your command? Even with sas disk, there are ppl who complete a plot in 2 hrs or less.

./chia_plot -n 1 -r 32 -u 128 -t /mnt/tmpfs/ -d /data/raid01/ -p xxxxxxxxxxxxxxx -f xxxxxxxxxxxxxxxxxxxxxxxxx
/mnt/tmpfs is 300G ramdisk
I have this CPU setup and plotting all everything in RAM takes 33min. So, check your SAS drives.

Hmmm, strange others can accomplish 80~90min plot with theses sas drives. Looking into it.
@edamame43 try something, put each SAS drive on an individual RAID 0 so you can test them individually and check which one is the bad performer. The thing is, if you have a bad performer and you create a RAID where that one is included the access speed tho the RAID will be the access speed of the slowest drive.

I did not use RAID. I have 4 sas drives connected through 1 LSI 9210 card( which does not support R0). I have started 2nd plot using the other 2 sas and see if it makes any difference.
install IT firmware for LSI 9210 card then each drive will be separate and create software RAID
make sure not to use NTFS in Linux

thanks, I'll try

Is that why it's so slow?
Specs: Dual E5-2690v1, Supermicro Inter C602 X79, 64G RAM 1600, 2 300G SAS drives as temp1 and temp2. on ubuntu total plot time is 33388 sec, about 9 hrs.
./chia_plot -n 1 -r 32 -u 128 -t /path/to/sas1/ -2 /path/to/sas2/ -d /path/to/finaldir/ -p poolkey -f farmkey
Phase 1 CPU usage is at 22%.
Did you manage to figure out the problem?
I have a similar problem Config 2 E5520 @ 2.27GHz 16 theards 2 SAS 300GB HP 15 000rpm, each in a separate RAID0 Controller HP P410 latest firmware

Tell me how to look for a problem?

There is no problem. SAS is too slow.

Hmmm, strange others can accomplish 80~90min plot with theses sas drives. Looking into it.
So you, too, found that they quickly plots?
There is a video on YouTube of how 24 plots are received on sas disks a day.
What did you decide in the end?
