Hi,
I'm accessing a Windows Virtual Desktop machine with both classic RDP client and also the WVD client app.
I'm also tracking with perfmon the "Remote FX Network" counters which includes both "TCP RTT" and "UDP RTT".
When connecting through the WVD client, looks like only TCP is used, and I see that the counters related to UDP are zero (makes sense).
However, when connecting with the classic RDP client, despite both UDP and TCP protocols are used, "UDP RTT" is always zero (which is impossible) and "TCP RTT" is flat with a value of 400ms (which is also wrong: it is too high because the UX is great and RTT ping avg. is 28 ms). The "TCP RTT" is never updated again.
See the screenshots:


How often are these counters updated?
Why these counters seem so wrong when using the classic RDP client? Please note I'm using the latest version of the client on a Windows 10, so RDP 8 is supported.
Thanks in advance
