After my original message I posted an addendum (https://mail-index.netbsd.org/port-arm/2020/07/23/msg006887.html) that was an iperf3 session run against a different iperf3 server (my pfSense gateway).  That one got similar speeds to yours above.

It's not clear to me why receiving from a quiescent laptop was a lot slower than from my pfSense gateway, but there you go.  (Note: receiving speed was not slow on the Raspberry Pi OS system.)

Cheers,

Paul.
