Wyse 3040 - WMS - Slow to VDA WinServ2016

Hello,

My configuration :

• VDA Windows Server 2016
• Citrix Virtual Apps and Desktops 7 1912 LTSR (last LTSR)
• I have a Wyse Thin Client C90LEW model 2011 => Ok for the connection with wnos.ini
• And i have a new model Wyse 3040 model 2019 => Ok for the connection with Wyse Management Suite

With my old wyse, no problem of slowness with my connection via a pnagent. Chrome opens normally and I can browse the internet quickly.

On my new wyse, I have a lag with each action on my Citrix environment, explorer, chrome ...
I tried to update my firmware from 8.5_024 to 8.6_303. The problem persists...

Has anyone ever had the problem?
Are there any parameters to specify on WMS?

Thank you
