Odd to say the least. Their system requirements are low, we even purchased a new PC (for one of the workstations) to see if that would help.
The new PC is a I5-7400 CPU 2.4 Ghz with 8 GB Ram so it is more than sufficient.
Requirements:
Processor Intel
Core i7, i5, i3 Intel Core 
2 Duo 2.53 GHz
RAM 6 GB (64-bit) | 4 GB (32-bit) 2 GB
Hard Disk 160 GB available disk space 80 GB available disk space
Optical Drive DVD RW DVD ROM
Network Adapter Ethernet 100/1000 Ethernet 100/1000
Monitor 19 LCD/LED (or larger) 17 LCD/LED
Video Adapter 32-bit, 1024 x 768
or higher resolution capable
16-bit, 800 x 600
or higher resolution capable
Sound Standard sound card Standard sound card
USB 6 available USB 2.0 Ports 4 available USB 2.0 Ports
Operating Systems (32/64-bit) Windows 10 Professional
Windows 8.1 Professional
Windows 7 ProfessionalYou can try setting up a Windows 10, 8.1 and 7 VM on the host and see if the performance is still slow.
Is it meant to be accessible via network shares?
Even worse - the vendor declares that access is through UNC path only, not a mapped network drive.. lol

@CCWTech what versions of SMB are enabled on the server and the clients?
-
I'm aware.

I haven't tried SMB 1 yet. Is that something that needs to be done on physical, hyper-v, and clients?

I'm curious as to what's currently enabled?
-
So the app is fast when using local storage and slow when using network storage? Seems like a not unexpected behaviour.

Just defaults.
Does SMB1 need to be enabled on ALL servers (Physical, Hyper-V Applications) and then all clients?
If so, can that be done when they are in production?
-
Temporary exclude the software directory and/or processes of that software from Windows Defender AV on server to see if that helps.

Except that it is. Of course running it locally with be always faster, but I'm talking about very significant slowdowns. I said above that I have done several of these servers for clients that use the software and have not had this issue.

Have you looked for things like a broken switch, unnecessary route hops, high latency between nodes, packet loss, or things of that nature?

need? I would hope not, but I don't know.. Have you confirmed what is actually enabled? What's the output of
Get-SmbClientConfigurationandGet-SmbConnectionon both the hosting VM and the client computers? -

Right, but difference now is - Windows server version and Hyper-V version? what about hardware differences?

Server 2016 is new. They all have been 2012 R2 and earlier. However the vendor says they have tested 2016 and had no problems. I don't know how much testing they have done with hyper-v (although they so support it).
Hardware is essentially the same setup.
-
When possible, you should have a copy of the data so you can just restore it to a test location for something like the following.
Windows 10 PC (Desktop/laptop hardware) put the data there and access it using the same client machine via the same switch as the server uses, see if there is a difference.
Then test the same setup with Server 2016 on that hardware.
-
I believe you said that you put the data directly on the Hyper-V host and shared it? if so, what was the outcome?
I also recall that you shared it from the VM, and accessed it on the Hyper-V host via that share, and it was slow - is that still the case?

It is still slow when running the app on the physical server from the hyper-v (apps) server.
I have put the application on a directory on the physical server and shared that out for testing. More to come...
-
I gave the wrong command.
Get-SmbServerConfiguration
This one will tell you what SMB versions you have enabled for serving up shares. Only needed on the server side. -
