Hello,
Started a conversation over on Reddit, figured I would post over here too. I am fully aware of the limitations on Wifi, throughput, expectations, etc. Hear me out...
FreeNAS: Freshly upgraded 9.10 installation.
I created a 10GB file filled with random content. Copied to 3 separate machines, rebooting in between. Source is a laptop and it has 8GB RAM connected with 802.11AC. Wired speeds are normal and included.
Timed results in copying a 10G file

Screenshots:
What started all of this is that I just got a new Ubiquiti AC-Pro and expected it to be "faster" than my Cisco N AP. Doing iperf to a test box single threaded I get ~280mbit. Move it to 4 threads, and I max out the AC on my laptop (approx 450mbit, expected at ~800mbit link speed). So, while initially I suspected this to be a throughput issue at the Access Point, it does not appear to be the case. That is why I tested against a Windows 10 box as well as my Qnap and was shocked to see it go faster.
What I have tried so far...
When I set the Minimum back to SMB2, and the max to SMB3, then I can view the share. When looking in the logs, it looks like it negotiated at SMB3_11 (expected).
Thoughts on where to look next? I want to say it's networking too, but the fact I can copy to the W10 as well as the Qnap which is running Samba... at what I would expect an AC link to deliver, somewhat says otherwise, no?
Thanks!
