I do also see around 20% additional throughput for HTTP/1.1 connections using a parallelism of 20 in the above test (different parallelisms produce very similar results). HTTP/1.1 - 60k/s HTTP/2...

We have seen very similar behaviour in our WebFlux project and are currently trying to create a minimum reproducible sample. Which Reactor instrumentation mode are you using (default is DECORATE_ON_EACH)?...

I see the same behaviour if using DECORATE_QUEUES, but using DECORATE_ON_EACH as the Reactor Instrumentation type preserved the trace id.
