Description

Windows qlog does not look good. Large latency in the RTT measurement and the session takes ~300ms with a lot of gaps of inactivity on a recording with just 2 streams.

Here's the qlogs:

Research direction

Start by inspecting the attached qlogs.zip and comparing the Windows recording with the reported two-stream behavior, focusing on RTT latency and inactivity gaps. Trace the QUIC transport path used in Windows CI to identify where the approximately 300 ms session delay arises. Done means the cause is isolated and the Windows performance issue is corrected and verified.
