Network setup - Hyper-V

Got it! I have tried both. No noticeable change.

Tried disabling antivirus and maybe firewall on the workstation that is accessing the application?

@black3dynamite I should have by now, but no. Let me give that a shot.

I would then try accessing via IP and DNS to confirm if that helps too.

The way the app is installed is that essentially all the server is doing is hosting a file share. You place a shortcut to the .exe file on the desktop.
can you elaborate this bit. where the application files reside?! when you say access app via netwrok are you talking about a client server topology or are you doing something more exotic?!
-
Files are on a server (Hyper-V in this case). Quite literally on each desktop you navigate to the UNC path and do a right click on the main exe and choose send to desktop.
It seems fast when they are closed, but slow when they are open (and everyone is using it). They only have 9 PC's however. The server is way above min and even recommended spec's for the software.
Their network switch is a Netgear GS748Tv5 and I upgraded the FW to the latest version.
-
@ccwtech Is it the initial launch of the application that is slow or the navigation within the application? I assume this behavior happens on every computer? Are they all hardwired or wireless? Can you run an extended ping (ping -t) to the application server from a computer having the issues and make note what the response times are after hours vs. during hours. If you attempt to copy some files from the same UNC path the main exe is at to a temp folder on the local pc, what kind of file transfer speeds are you seeing?
-
Turning off firewalls and AV had no impact.
Initial launch and the app while in use is slow.
All PC's are impacted. All are hardwired 1 Gig cards and switches. Replaced all switches except the main switch
A ping -t shows <1 ms day or night
Transfer speed of a folder with files (about 300 Meg) is about 20 MB/s
I appreciate everyone's help here. It sucks when you set up a brand new server for a client and they want their 10 year old server back.

What OS was on the old server vs the new one? Wondering if it may be an SMB issue if they are going over a UNC path?
-
Going from 2008 R2 Standard to Server 2016 Standard

20 MB/s seems horrible to me. My home network is much faster than that.

Hmmmm.. Are the workstations W7 or W10? Wondering if using different SMB versions may be an issue as well. I only mention this because I had a network issue a long time ago when I went from 2003 to 2008R2 and SMB was an issue until everyone was on W7 from XP.
Edit: - Also, are there any errors in the Event Viewer when copying large files or starting the app from a desktop?
-
Mixture of 7 and 10.
I should have tried this earlier, but I tried the application on my other VM (the domain controller - same physical box) and it's slow there as well. It's also slow on the physical box.
At least that eliminates a ton, but still doesn't tell me why it would be fast on the other VM itself.
-
I was thinking that my last post may be very critical in solving this issue. Any ideas to help?

Just trying to get your setup correct, Multiple 2016 VM's on one 2016 Hyper-V host. 1 RDS, 1 FS and 1 DC?
Is app installed on RDS or FS server?

1 Physical Box with 2 VM's
1 - DC/DNS/DHCP
1 - File Server/RDS Server (Application resides here) -
And when it worked better - what was that setup?

1 - File Server/RDS Server (Application resides here)I am guessing they are are all on the same vswitch?
Is it slow when you access the app from the DC?

OLD vs. New
OLD:
Intel Xeon E5245 2.33Ghz (DUAL) / 16 GB Ram / 7,200 hard drives in RAID 1 / Broadcom BCM5708C NetXtreme GigE
VM1 - DC/DHCP/DNS - 8 Virtual Processors, 4 GB Static RAM, - Application resides on this box (file server)
VM2 - RDS Server - 5 Virtual Processors, 6 GB Static RAM - Used to remote into and run the application from VM1NEW:
Intel Xeon E5-2640 v4 2.4 Ghz / 64 GB Ram / 10,000 hard drives in RAID 10 / Intel I210 GB
VM1 - DC/DHCP/DNS - 1 Virtual Processor, 4 GB Static RAM
VM2 - RDS Server - 4 Virtual Processors, 24 GB Static RAM - This is RDS box and also where the application resides -
Maybe the issue is that SMBv1 is not available anymore for Server 2016 could be affecting the performance accessing over the network.
