@ccwtech , what kind of file transfer speeds are you seeing?

I was wondering this as well. That will rule out the application or point to another problem.

Transfer speed of a folder with files (about 300 Meg) is about 20 MB/s

20 MB/s which seems VERY slow to me.

Is that with IP or DNS?

DNS I will try via IP

The implementation of VMQ was rolled out so badly.

I ranted on it in a thread more than a year ago.

You can disable it on the NICs quite easily.
Get-NetAdapterVmq | Disable-NetAdapterVmq

If you haven't done this, I'm going to suggest this again. Run it on the Hyper-V host. I've seen this clear up issues on both Intel and Broadcom chips.

Yeah, 160 Mb/s on a 1 GB line, that is pretty slow.

I know I've suggested running this several times since it was first mentioned.
How about showing the output for

 Get-NetworkAdapterVmq

Actually, that's not all that bad. SMB is insanely chatty.

I can typically transfer over 500 Mb/s on my network between Win10 and Server 2012R2.

Great question, I've never dug into it.

With SMBv1 you won’t get that... also do you have SSDs?

SSD = nope in server, yes in desktop

Get-NetworkAdapterVmq

I just get an error saying that's not a recognized command. That is for powershell right? (I also tried command line)

CCWTech

I have also copied the application to the physical server to do some testing.

Thanks.

Running that command produces no output. It just goes to the next line.

Vmq not enabled.

Did your run that on the Hyper-V host or the VM? or both?

What is the current status of NIC teaming? do you have one on the Hyper-V?

Well that's good and bad... Good that it's not enabled, but bad that that's not the solution.
