I can speak to iperf 2 but not iperf 3. It depends on the goals. If the goal is to test throughput only, then the hardware requirements are driven by the ability to saturate the link under test. If the links are 10G or above, and speaking for iperf 2, the -P option will use multiple traffic threads so more cores will help.
If the goals include measuring one way delay (OWD) then the hardware needs a way to synchronize the system clocks to a common reference. We use the GPS atomic clock since it's somewhat available over the globe. In general, iperf users (and blog authors) are behind. We find that latency really needs attention from the industry at large. Seems like too few understand this aspect of network performance (and user experience) and seem to be stuck on throughput-only measurements.
