Does anyone have any idea why I am getting pool SMB transfer speeds in the region of 5MB/s?

Currently only using the 1GbE links in the server for SMB but I will be migrating to the 10GbE links fairly soon when my new 10GbE switch arrives for my home lab so I need to resolve this speed issue asap. upload_2017-6-12_15-42-34.png

Has the speed dropped to 5MB/s or is this new behavior?
What does /usr/local/etc/smb4.conf look like?
Anything in /var/log/samba4/log.smbd?
If you turn off LAGG and use only single gigabit link, does performance improve?

This is new behaviour my backup box is still able to saturate 1GbE both read and write and it has way less resources.

Post the /var/log/samba4/log.smbd. Depending on what's going on in your system, the last 10 lines of the log won't necessarily contain useful debugging info.

I have powered off all of my VMs which are running on another pool comprised entirely of SSD and I am going to reboot.

OK, So post reboot with NO Tunables the transfer speed is still around 5MB/s

@Simon Sparks : Have you run iperf to test the network speed?

Its not a network issue, I have 2 FreeNAS boxes connected in exactly the same way and nothing has changed except and upgrade to FreeNAS-9.10.2-U5 which has been fine on 1 box and the other box has decided to become slow....

Best to rule it out anyway. Please post results of iperf.

Edit: While you're at it, please post the output of ifconfig too.

Run iperf with lagg enabled.
Run iperf with lagg disabled.
make sure to run it with freenas as the client and as the server, both directions is important.

Saturating a gigabit network is super easy to do, the hardware specs do not matter. Just a single hdd can do it.

Does anyone know why this is happening ?
