"IPerf 2 <https://sourceforge.net/projects/iperf2/> is different from the iperf3 <https://github.com/esnet/iperf>. Each can be used to measure network performance, however, they DO NOT interoperate. They are completely independent implementations with different strengths, different options, and different capabilities. Both are under active development"
iperf 2 latency & one way delay (OWD) results are reliable assuming one has synchronized the clocks to a common reference. Tests such as --bounceback don't require clock sync as it uses a TCP round trip measurement, i.e. write() to read() and back.
