Any idea how this differs from iperf?

  iperf3 is a link “speedometer” – spin it up between two hosts, crank -P or -u -b, and it tells you max TCP/UDP throughput (and jitter/loss if you like). 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.
