Session delays on Windows 2019

Question

Hello, does anyone else facing issue with slow user sessions after migrating from windows 2012 R2 to windows server 2019?

 

After we completed the migration, users started reporting slow user experience but we have checked:

  1.  Local disk free space - Clean
  2. CPU & Memory - Clean
  3. Procmon logs - Clean
  4. Citrix Optimization Tool

 

Does anyone know face something similar, and if yes, how did you resolve it?

Narrow down as to what they mean by slow user sessions. 

 

Are you talking screen redraws?  File copies?  Mouse movements?

 

Are the users on-site or remote?

 

Do they go through a netscaler or VPN?

 

User are on-prem, although, logon time is slow (we have followed WEM optimization Citrix Article) and compare to Win2012R2 their logon time has increased dramatically. 

 

Additionally, "Interactive Session" time has also been dramatically increased compared to our Win2012R2 image. 

 

Our users they connect to their VDI session via CWA connection.

Spectre/Meltdown are enabled by default with Server 2019. Due to our hardware limitations we had to disable the fix via registry. Even with that said, 2019 is slower compared to 2012 R2. Microsoft made a lot of changes around the OS handles things, due to security and our applications run slower on the OS.

Thank you for your reply. I will keep that in mind and try to see how I can optimize this.
