extrem Slow Performance after activation of Virtualization-based Security (VBS)

[Holger Scheele]

Hi Folks.

We have a Windows Server 2022 Citrix Farm. Alle Server on VMWare 8. Citrix LTSR 2203 CU5. Workspace App on WTS is 2405.10

Published Desktop, Published Apps on the Desktop - vPrefer is set to "Allow all apps"

 

When only one User works on the Server, the Perfomance is OK.

But when there are more then one User working on the same Server, the Performance is terrible.

Outlook has everytime 10 Second not responding. Mails need 10-15 Seconds to open.

Navigate in the Explorer is nearly impossible.

 

After turn off VBS in VMWare, the Performance is always OK.

 

Anybody an Idea what my Problem is ?
