So the followup to this on networking issues is that I don’t think everyone involved is being honest.
As best I can tell, forcing hosts in full-duplex mode is a non-starter. The switch can be set that way on all ports
but the hosts seems to do fine in half-duplex or autoselect, depending on the OS involved, whether it’s OS X
or FreeBSD.
The source for these huge transfers is the first system shown above and the destination is on a wireless link. It would be nice to see better than ~10 Mbits but I don’t know what magic I need for that to work. I’ll just let it go for now.
