Comparison between display settings in Citrix HDX

Hi everybody,

Last Citrix Synergy (2017) in Orlando, Benny Tritsch and Ruben Spruijt presented the following session:

SYN303: Independent Citrix experts deep dive on Remote Graphics, user experience and GPUs.
This session was among the top 10 of most popular sessions of Synergy 2017, if you didn’t see the presentation you can watch it on-demand here.

In this presentation the new Remote Display Analyzer (RDA) version 1.6 was announced which will be released soon. This version includes numerous new features like a screen capture button and a GPU add-on (available for all display protocols Remote Display Analyzer supports). More about this new RDA version soon.

Also shown in this presentation where the results of a short comparison between 3 major display settings currently available in Citrix HDX. In this blogpost I will show you how this comparison was made together with some key findings. The display settings where evaluated in real-time by playing the exact same video three times while live switching between the following settings:

  • Video codec not in use
  • Video codec for the Entire screen
  • Video codec for Actively changing regions

You can watch the comparison here:

The result of each setting is shown below:

Some key findings from this short comparison:

  • The total send frames where nearly the same
  • During the test I noticed no big difference in user experience while playing this short 720p HD video
  • Video codec not in use has the lowest impact on CPU but as you can see the bandwidth consumption is higher then the other two
  • Video codec used for the entire screen (with text optimization) gives the best result on bandwidth consumption, but this comes with a higher CPU usage
  • Video codec used for Actively changing regions results in a very good balance between both CPU and bandwidth consumption

Disclaimer:
Please note that this results come without warranty of any kind and are my own interpretation based on above test. The results may vary based on factors like workload, bandwidth and the infrastructure you are using. Please always test settings in your own environment to decide which configuration fits best in your scenario.

Remote Display Analyzer for HDX 1.4 released

Hi all,rda

I want to begin with a big thank you for all the positive feedback about Remote Display Analyzer (RDA) and also a very big thanks to the members in the sponsor program, this really helps to drive RDA forward and to help balance the amount of time spend in this project by giving something back to the family. So thank you very much for becoming a sponsor!

If you read about Remote Display Analyzer for HDX for the first time, this tool will help you decide which display settings are the best for your Citrix environment. RDA will help you:

  • Visualize Citrix HDX display modes, this will give you a better understanding of all the settings and what their effects are in real-time
  • Only show you settings that are applicable for the active display mode
  • Live switch between display modes and settings
  • Give insight in consumed resources (CPU, Memory, Bandwidth) and compare them to other display modes while running the same workload
  • Troubleshoot display issues

What’s new in Remote Display Analyzer for HDX 1.4

Below you will find a print screen of version 1.4:

1.4 printscreen

As you can see there is a new section added called Total Analytics. This will give you insight in the consumed resources after running a specific workload. For example you can run your graphic intense application, your business applications or play a video and measure the total consumed bandwidth and the total frames that are send to the client. The average bandwidth counter will give you an indication what the average bandwidth consumption (per second) was while running your workload.

RDA will now also show you the detected (available) bandwidth between the remote environment and your client, there is a reset button which you can use to reset the total analytics back to zero so you can start analysing just before running your workload.

The HDX policies are updated to reflect the changes made in XenApp\XenDesktop 7.9 and version 1.4 also contains numerous fixes and improvements.

Remote Display Analyzer for HDX 1.4 is now available on the website. All existing sponsors will receive a mail automatically containing their new sponsor unlock password. If you are a sponsor and didn’t receive this mail, please send a mail to info@rdanalyzer.com and we will take care of this as soon as possible. New sponsors will receive a personal unlock password automatically by filling in the sponsor form on the website, thanks for your support and feedback!
