Guilty. Blame it on oldtimers.

They are a Netgear GS-108 for the managed one, about 4 years old, and
another unmanaged Netgear GS something, its up on a shelf and mostly out
of sight in the garage and its close to a decade old as it started life
here, and got moved to the garage when I bought this one. Might be both
will handle ipv6, but any ipv6 connectivity stops at the cable modem so
I generally keep it disabled.

Depending on the driver, that or 1000M.

All active are green.

Anyway, I found an answer, iperf says the net is fine. That leaves the
write speeds of the SSD's on the other end. And I can't fix that.
So lets close this thread.
Thanks Dan
