Operating system：Windows Server 2019 Datacenter
GPU model：RTX 3060
NVIDIA graphics driver version：31.0.15.2737
Headsest/Device used：Pico Neo 4
Steps to reproduce the issue：
Network:
iperf3 test result is 42.6Mbps
Log files with verbose mode enabled from the client and server.
logs.zip (6.3 MB)
apologies for the delay in getting a response, much of the team was off for weeks across the holidays.
So, first just to note, iperf test is good for sort of a baseline, but it’s like running any web bw test, it’s an averaged snapshot. Also noting that for best performance, cloudxr is looking for I believe 50Mb per eye – that said, it should still run stably at something lower. What is your overall network topology like? What wifi, what router, normal ping to server, what server host, etc. Something in the setup is at the root of issues.
Second, the server log clearly indicates latency and bw issues/fluctuations. Latency never hits 100, bw is all over the place. Again, network problems.
Third, I’d need someone with more expertise, but the QoS logs certainly indicate overall network quality fluctuating over time. Further, while there are some truly random spikes, I’m good at identifying patterns, and it struck me pretty quickly that there is a spike in frame delivery above 400 every 12-14s, throughout the run. Once again, there’s some kind of network/connectivity issue there. Something jamming up the network on a pretty precise periodic cycle.
I haven’t looked at the ETL as yet, but I imagine it would paint a similar picture.
I’ll see if someone with a better eye for specifics might be able to look a bit more into your situation after you provide some additional details as to the end-to-end network setup and server setup.

Oh, forgot to note that jitter value is high overall, and has some extreme spikes, which also clearly indicates some root networking issue(s) under the hood.
If you’re running Windows 2019 Datacenter you’re likely streaming from somewhere not local. Given the noted spikes within the Log, I would advise seeing what happens when streaming from your local network first given it may offer more bandwidth than the 42Mbps reported.
