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.
I can try that, but how would that be different than running it on the other VM (Server 2016) that is the DC?
Well if its still slow when trying to access the application from the DC too then never mind my previous response. Just wondering if its a hardware or driver issue on those workstations.

That's the $1,000,000 question...
-
It would not hurt to set up a Windows workstation as a VM and do a test to make sure that you’re not having some kind of problem with that Windows server vm

I'm willing to try almost anything right now. I just was wondering what that would show... Booting up a VM shortly.
-
@dashrender I have set up another VM (In this case Windows 7 Pro 64 bit with SP1)
It's slow on this machine as well.
Anything outside of the VM where this app runs is slow (virtual or physical machines).
I haven't enabled SMB 1, does that need to be done on the VM and Physical machine?
-
Ideally you'd want to use the very latest SMB protocol. But that doesn't appear to be the issue regardless.

Ok, it had been suggested here.
I'm just looking for anything else to try at this point.
-
Maybe there is a DNS issue and things are stalling on resolution?

It was still slow via IP too.

Oh, so much for that theory.
-
I forgot Windows 2016 includes Windows Defender now. Try accessing the application with Windows Defender turned off on the server.

While this shouldn't be the case, why not try it. Windows 10 1709 does have SMB v1 disabled by default, so you'd have to do both Server 2016 and Win 10 1709. I'm not sure if a WIndows Update turns it off on any other Windows desktop or server version.
-
Since the host is a a full install of Windows Server 2016 - make a copy of the data folder and map it to a workstation and see what happens as another test.

@ccwtech said in Network setup - Hyper-V:
Their network switch is a Netgear GS748Tv5 and I upgraded the FW to the latest version.
Can you show us the config of the switch for the ports the server is plugged into, as well as one of the PCs?

@i3 said in Network setup - Hyper-V:
@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.
-
@ccwtech said in Network setup - Hyper-V:
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.
https://mangolassi.it/topic/8358/i-hate-vmqYou can disable it on the NICs quite easily.
Get-NetAdapterVmq | Disable-NetAdapterVmqIf 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.
