rtt_qos1_fixed

At 1,000 requests/s against a neutral echo, what is the application round trip?

rtt · QoS 1 · 256 B · 1,000 requests/s · MQTTv311 · how it is wired

awscrt · aws-c-io does not expose TCP_NODELAY, and a trace of the library's connect shows it never sets it, so Nagle's algorithm stays on. A QoS 1 round trip then waits tens of milliseconds, against hundreds of microseconds at QoS 0, where no acknowledgement is pending: the pattern of Nagle's algorithm waiting for a delayed ACK. This is the library as shipped, reported as measured. It says nothing about the library's publish or receive cost, which the other points show.
