Hi,
Testing out writing from my Manjaro system to TrueNas 3 x old WD drives [for testing before I get shiny new ones] in RaidZ1 (other specs in signature).
I mount the NFS share and use DD to copy a file to the NAS
I'm getting only about 70MB/s for this 1GB file.
If I turn of write sync on the NFS share then I get up to about 180 MB/s.
(Incidentally this is a dual boot system and botting into windows I get around 250MB/s write to the NAS!)
Surely I shouldn't have to turn off write sync to take advantage of the 2.5Gbe?
How can I improve the speed and get it closer to Windows SMB performance?
I've read a lot on these usual forums about ZIL and SLOG etc.
Do I really need an SSD to try to offload the additional writes for the sync from the main pool or am I missing something obvious?
