Hi Karel
Thank you very much for your hint.
Yes, I used FreeBSD 13.0 for final performance testing (scp transfer and
iperf3).
Before I run some tests with stable FreeBSD 12.0 but the performance was
much lower (even still approx 3 times better than OpenBSD 6.4). FreeBSD
12.0 recognized less

Hi Stuart
Thank you very much for the link.
The total ssh based performace depends strongly on the server hardware

For the "fastest" test configuration (server hardware / installed OS) I

Running dd with "/dev/zero" and "/dev/null" gave me back a very good

SATA 3 wire speed is 6G/sec and realistically 500MB/sec raw rate

Anything over that is an artefact probably from a cache somewhere.

filesystem, hardware issues, scheduling, etc.), please let me know.

12x slower? That's insane. What are you
on Linux, also no filesystem cache, so depending on your HDD with
scp you may be hitting the max throughput for the FS, not the network.
