(Admittedly, it has been a while since I have done it) It did feel odd that there was not a mention of time discipline for the client/server and the impact on finer-grained stats. Perhaps, at least, mention that NTP (or, ideally, PTP, but that is a fair bit more involved) is strongly recommended to be running and stable (NTP's own jitter being low)?

tcpulse is a fine-grained traffic “microscope” – you dial exact CPS or concurrent sockets, spray dozens of targets from one client, and get p90/p95/p99 latencies per flow.
Use iperf3 for a quick bandwidth check; use tcpulse when you need repeatable, controlled connection patterns and detailed latency stats across many backends.
