Wyse T10/3040 Slowness on Citrix with Browser

Hi,

we have many Wyse T10/3010 thinclients which were not updated in the last years.

Most of them are still on firrmware 8.0_210. During the tests of firmware 8.6_024 in different Citrix environments we found some slowness if an internet browser is running.

We have three different environments.

1st:

everthing is running fine with 8.0_210 and 8.6_24

• Storefront-Version: 7.6 LTSR CU3
• Netscaler-Version: N/A
• Citrix Version: 7.6 LTSR CU3
• PVS: 7.6 LTSR CU3
• Loadbalancer: KEMP

Windows 2012 R2

2nd

Internet browser (typing, reaction to clicks) Start menu and switching between programs is slow, other apps are working fine

• Storefront-Version 7.15 LTSR CU4
• Netscaler-Version: N/A
• Citrix Version in cloud, VDA: 7.15 LTSR CU4
• PVS: 7.15 LTSR CU4
• Loadbalancer: KEMP

Windows 2016r2

3rd

everything is very slow; typing in all programs (character takes up to 60 seconds to appear), switching between apps (30 to 60 seconds), even in internet browser, mouse clicks, start menu

• Storefront-Version: 1906.1.0.31
• Netscaler-Version: N/A
• Citrix Version in cloud: VDA: 1906.1.0.31
• PVS: 1903.0.1
• Loadbalancer: N/A

Windows 2016r2

We are using the same wnos.ini for every environment, only difference is the PnliteServer.

Fun facts: T10 with 8.0_210 it works fine in every environment, also D10D/5010 and 3040 with 8.6_x are working fine

It would be nice if someone has an idea about that issue.

Thank you!
