Azure desktop UFT application issue

Question

While running the UFT application on Azure in a virtual desktop, the SAP logon page in Google Chrome takes about a minute to load, but Citrix refreshes in seconds. How can I fix this issue in Azure?

Answer 1

Hello @Malendraswami Hiremath ,

It sounds like your SAP logon page in Chrome is really slow on Azure Virtual Desktop (AVD) compared to your Citrix setup. Usually when something performs fine in Citrix but lags in AVD, the culprit is network path or proxy settings rather than UFT itself. Here’s a quick trouble-shoot plan you can try:

Measure network latency & path

• RDP into one of your AVD session hosts and run:

   Test-NetConnection -ComputerName <your-sap-server> -Port 443
ping <your-sap-server>
tracert <your-sap-server>

  - Compare the results to what you see from your Citrix servers. If your round-trip times are much higher from AVD, you’ve found your bottleneck.
  
  Check proxy or web gateway settings in Chrome
  
     - Open Chrome’s Settings → System → “Open your computer’s proxy settings” and verify you’re not accidentally routing through a slower proxy in Azure.
     
        - Mirror the exact proxy configuration you use in Citrix.
        
        Review your Azure ↔ on-prem connectivity
        
           - If your SAP system is on-prem, make sure your AVD VNet has a Site-to-Site VPN or ExpressRoute circuit to your datacenter rather than hair-pining traffic over the public internet.
           
              - If you already have ExpressRoute, validate your NSG/UDR routes aren’t forcing SAP traffic back out to the internet.
              
              Optimize session host placement & sizing
              
                 - Ensure your session hosts live in the Azure region closest to your SAP backend.
                 
                    - Confirm you have sufficient CPU/memory on the VM SKU for browser-based workloads.
                    
                    RDP client performance tweaks
                    
                       - In your Remote Desktop client’s Experience tab, disable features you don’t need (e.g. audio, visual styles).
                       
                          - Consider enabling UDP transport in the Windows 10/11 RDP client for better interactivity.
                          

If after those steps the page is still slow, it’ll help to get more details:

• Which Azure region are you hosting your session hosts in? • How is your AVD VNet connected to your SAP network (ExpressRoute, VPN, public)? • Do you see the same delay if you RDP directly into the session host and launch Chrome locally? • Are there any corporate web proxies or firewalls in the path? • What VM size and OS image are you using for your session hosts?

Once we know more about your network topology and session host configuration, we can narrow down the fix.

The behavior points to connection or session host performance issues in Azure Virtual Desktop rather than UFT or SAP itself. Focus on reducing latency and ensuring the VM has enough resources.

1. Check and optimize network latency
   • Measure round-trip time (RTT) from the client network to the Azure region where the AVD session host runs.
   • RTT should be <150 ms; above 200 ms can noticeably impact web apps like SAP in Chrome.
   • If RTT is high, move or recreate session hosts in the Azure region closest to the users and verify that firewalls, ExpressRoute, or other network devices are not adding excessive delay.
   • Use the Azure network latency statistics to confirm the best region and re-check every few months as recommended.
2. Verify local internet stability and bandwidth
   • Ensure the user’s local internet connection is stable and not saturated or rate-limited.
   • If bandwidth is constrained, reduce competing traffic or upgrade connectivity, following the Remote Desktop network guidance referenced in the documentation.
3. Check VM CPU and memory utilization
   • Use Azure Virtual Desktop Insights or Azure Monitor performance counters on the session host to check:
     • Processor Information(_Total)\% Processor Time for CPU
     • Memory(*)\Available Mbytes for available memory
   • If CPU is consistently high or available memory is low during SAP/Chrome usage, scale up to a larger VM size or add more session hosts to reduce contention.
4. Use AVD diagnostics to compare sessions
   • Enable and review Connection Network Data Logs in Azure Log Analytics.
   • Compare connection quality (latency, bandwidth) for sessions where SAP is slow vs. normal Citrix performance.
   • If logs are missing, verify diagnostic settings and VM configuration, and ensure the session is active while testing.
5. If the issue persists
   • Use Azure Virtual Desktop Insights to look for broader deployment or connection issues.
   • If after optimizing latency and VM resources the problem remains, open a support request with Azure Support for deeper investigation of AVD session performance.
