Slow Performance issue after installing Nvidia Grid Tesla P40 vgpu drivers on XenDesktop VDIs


Zoran Timotic1709161822

Question

Hello,

 

actually we are working on a project with cad virtualization(HDX3DPro).
i have a big performance issue with my Citrix/Nvidia Grid Infrastructure
the problem starts after we install the nvidia GPU drivers in the VMs/VDIs.
different applications are very slow after the driver installation
for example solidworks(CAD Application) oder a Sage Client(ERP Application)

 

Before the installation everything is OK!!!!!

 

this is our infrastructure:
2 x Dell PowerEdge Server 740
each server has two NVIDIA Tesla P40 Grid cards
we tested it on Xenserver 7.1 / 8.0 / 8.1 full patched
we tested it with vGPU 9.2 (431.79) und 10.1 (442.06)
the problem exists with different nvidia profiles 2Q or 12Q
the VMs working with Win10 1903, the problem is also there with Win10 1909
the problem exists with 32GB RAM or if you assign a lot of more RAM
the problem is also there with only one vm on the server at the same time
you can see the problem directly in the console or in a citrix session(same impact)

 

it's difficult tocheck if this is a citrix or nvidia or a combination of both issue


we tried a lot of things but at the moment the ideas run out ;-(

Do somebody have ideas for us or the same impact?

 

 

thanks a lot


Zoran

Sorry for bring back this topic on top! Maybe someone is searching for these issue in future. I know probably the solution of this issue. If you install vGPU without a proper license nvidia limits to 3 FPS. It depends on your setup but often vGPU is used not for the entire screen/desktop. So these issue is only in application which will use vGPU.

 

Maybe this helps someone where is stumble about this thread.

Hi,

 

How are the applications "slow"?

  • Do they start up slow(er)?
  • Do they respond slow(er) to interactions with the mouse/keyboard?
  • ....?

In any case, best practice is to install the NVIDIA drivers before installing the Citrix VDA, because then the VDA will enable the NVIDIA GRID and HDX 3D Pro functionality.

If you install the NVIDIA drivers after having installed the Citrix VDA, then these steps need to be done manually. See:

https://docs.citrix.com/en-us/xenapp-and-xendesktop/7-15-ltsr/graphics/hdx-3d-pro/gpu-acceleration-desktop.html#install-and-upgrade-nvidia-drivers 

So I would reinstall the Citrix VDA as a first step.

Next would be to also look into what Citrix (graphics) policies you have set, because these will also impact the experience.

 

Best,

 

Koenraad

Hello,

 

thanks for your reply.

 

it is diffucult to describe at the moment i have two different applications with performance issues.

for example different actions in the applications need 1-2 secs longer then without the vgpu driver

 

it looks like that different actions take a little bit longer to show new masks/windows

i tested with or without vda but the issue is the same.

 

i tried this GfxDisplayTool.exe -vd enable but no change...

 

at the moment it is very difficult to check if it is a citrix or nvidia issue

Did you properly set up a Citrix policy for HDX3DPro settings?

Or check that the license is configured on the master at least?
