Truenas samba file transfer on 10Gbps ethernet on windows 10

[Amudhan]

I have a zpool with RAIDZ2 12 drive x 2 vdev pool, exposed dataset as samba share. Truenas scale server and Windows 10 client both connected on 10Gbps Ethernet.
When I transfer file from windows to truenas samba share transfer doesn't goes beyond 160 MB/s. I was trying to tune samba.conf file with "socket options" but
getting following error "socket options is a blacklisted auxiliary parameter. Changes to this parameter are not permitted".

How do I tune the config to get good speed by using 10Gbps network ?

I am trying transfer single file of 2GB size.

You need to list the complete specs for your system according to forum rules - otherwise there's nothing substantial to debug on.

What's the result when you test with iperf3 ?

Sure, this is my config.

CPU : Xeon E3-1270 v5 3.6 Ghz, 4 core HT support
MBD : X11SSH-CTF
RAM : 64 GB DDR4 ECC
HBA : On-board LSI3008 SAS3
Chassis : Supermicro
Ethernet : On-board Intel X550 10Gbps x 2
Backplane : SAS3
OS drive : Intel 80GB SSD SATA
Storage drives : 24 x HGST 6 TB SATA 3.5"

Iperf3 report from different machine each are connected to 10G ethernet and 10G Switch.
