Research direction

Reproduce the report on FreeBSD 14.1-RELEASE-p6 with bandwhich 0.23.1 during a single ZFS send stream over SSH. Compare bandwhich with systat -if 1 and the switch or router measurements; done means identifying why bandwhich reports roughly one quarter of the transferred rate and correcting the discrepancy.
