We are digital librarians. Among us are represented the various reasons to keep data -- legal requirements, competitive requirements, uncertainty of permanence of cloud services, distaste for transmitting your data externally (e.g. government or corporate espionage), cultural and familial archivists, internet collapse preppers, and people who do it themselves so they're sure it's done right. Everyone has their reasons for curating the data they have decided to keep (either forever or For A Damn Long Time (tm) ). Along the way we have sought out like-minded individuals to exchange strategies, war stories, and cautionary tales of failures.

I'm trying to figure out what could be causing the bottleneck on my NAS. By my calculations I should be able to easily hit over 1000 MB/sec sustained read but I don't know why I'm not. Any useful troubleshooting advice would be appreciated.

System:

OS: TrueNAS-SCALE-22.12.2

CPU: Threadripper 1950X

RAM: 128 GB DDR4

Network: 10 Gbit (Intel X710-DA2 -> Mikrotik CRS317-1G-16S+RM -> AQUANTIA AQC107)

Controller: Adaptec PMC ASR-72405

Drives: 8 Seagate Exos X20

ZFS Pool Config: 2 VDevs (4 drives each) in RAIDZ1

Why his numbers are right on the money. Need another vdev to break the 1k mark. Especially if looking for consistent over 1k numbers.
