Hi,
Super happy with Scale having been running TrueNas/FreeNas for some years now however I have a performance issue I just cannot fathom.
Issue is with read performance whether that's SMB/FTP or any other protocol is way underperforming (or so I believe based on hardware specs etc).
TrueNas server is on 10Gb links with a 10Gb switch and desktop is on 2.5Gb link.
Writing files from Desktop to NAS will saturate the 2.5Gb link of the desktop machine however copying files from Nas to Desktop (even multiple files) I cannot get more than 800Mbps so not evening hitting gigabit speed. I get the same results whether using a spinning disk or ssd based pool.
Iperf3 show 2.5Gb/s both directions so the network doesn't seem to be an issue.
dd tests (compression off) show write speed of 351MB/s and read of 417MB/s for the spinning disk pool so more than enough in both directions for the 2.5Gb link from desktop.
Spinning disks are a 5 disk RaidZ2 and SSD's are a pair in Mirror, all tests to/from desktop (Win10) used PCIe 3 NVME.
At this point I've run out of ideas, does anyone have any suggestions about what to look at next please?
Hardware:
Mobo - ASRockRack D1541D4U-28TR
RAM - 32GB ECC
HBA - LSI SAS3008 (IT Mode)
HDD - 5 x WD Green 5400RPM
Nic - Intel X540
Many thanks,
