Anyone have any pointers for optimizing a ThinOS 9.1?
I am configuring a brand new Server 2022 Citrix environment. We are using nvidia RTX 8000’s in our servers. I do have the licensing for nvidia GRID running and the VM does pull proper license.
Everything seems to run great in the session, except when I start to run videos from YouTube or get into video calls in Teams I start to notice my ICA RTT increasing. I’ve seen it hit as high as 12000 ms, which basically makes the session completely unresponsive. I’ve changed and adjusted about every policy possible that pertains to graphics and GPUs.At this point I’ve considered limiting the bandwidth of the session to see if forcing a restraint on the thin client can remedy the issue.
I know I’ve read others saying they having also performance issues with the 9.1 firmware over 8.6, however I’ve since noticed that HDX/Webcam redirection does not work from ThinOS 8.6 into a 64bit application running on the application server. I think for that to work you would require generic USB redirection and I thought that isn’t recommended anymore.
Would probably need to know more about the environment:
- What thin client model are you using, 3040, 5070, 5470…
- What Citrix VDA are you using, LTSR or CU?
- If your using Microsoft Teams, Citrix Workspace For Linux should have optimization built in so you shouldn’t be seeing Citrix HDX Camera it should be whatever the local USB or built-in camera is.
- Browser based audio and video isn’t optimized that would be leveraging Citrix HDX audio, there are some Citrix policies that can improve it, but Browser Content Redirection is the way you want to go for improving browser based audio and video.
Brian,
Sorry for delay in responsing. Never enough time in a day.
We are using Wyse 3040 Thin Clients. My test environment is the only ones using a 9.1 firmware. The version is 9.1.1131, I’ve tried newer versions and ran into different issues.
With v9.1.3, it was going to screensaver and then was unable to log back into an existing session, even after a reboot of the thin client.
With the latest version 9.1.5 it crashes back to login the moment I open Teams. I can log back in but it crashes again when trying to connect to my hardware, audio/webcam.I did confirm that it is not showing HDX Webcam but rather the actual name of the webcam device.
I’ll have to check my settings for the browser content redirection, not sure if I enabled that.Just feels like ThinOS is becoming harder to manage and setup as time goes on. Updates haven’t exactly felt like they are making things better, but here’s hoping!
From Dell Wyse Administrator and Release note Guides:
Citrix Unified Communications support on Wyse 3040 Thin Clients
Following features are not supported on Wyse 3040 Thin Clients due to client resource limitations:
● Video call or meeting
● Share screen
To avoid audio choppy issues during the audio call or meeting, users are recommended not to perform the following tasks:
● Move the application window frequently or quickly.
● Scroll down the Microsoft PowerPoint slide, Word document, Excel sheet, or a website page frequently or quickly.
● Play a video in an ICA session frequentlySo what your saying is I’m trying to fit a square peg through a round hole… I was wondering if the 3040 was underpowered to what I was trying to do. Appreciate you clarifying it for me. Shame we didn’t foresee the rapid adoption of Teams, we replaced all our thin clients less than 2 years ago and video meetings were not part of the design at the time.
Guess we’ll need to split our Citrix users into two groups now. Those that do video meetings and those that don’t.Thank you for your help.
