I have recently upgraded to Mac OSX Sierra 10.12.6 from Mavericks

I attempted to connect to my FreeNAS via (cmd + K) like I have done in the past, and typed in the IP Address (i.e. smb://192.168.1.xxx). I instantly found that my transfer speeds were awful (~2mb sec), as well as the hard drives taking ages to appear on the desktop, To note, I am connecting via Gigabit Ethernet.

After an initial investigation I found this article (https://dpron.com/os-x-10-11-5-slow-smb/), which apparently turns OFF "Client Signing" which is supposed to get things as they are supposed to be (~100Mb sec). Although many people say this fixed their problem, it didn't fix mine even though my Terminal tells me "signing_required=no", which means it has turned off "Client Signing".

My version of FreeNas is: FreeNAS-9.2.1.5-RELEASE-x64 (80c1d35)

Try a different SMB version in FreeNAS settings and do not enable jumbo frames, or if you do, do not go over 1500 if I remember correctly.

Try upgrading to latest version of Freenas, then enable the following VFA objects on all samba shares:
  • Catia
  • Streams_xattr
  • Fruit
Post your smb4.conf file as well
