--- Comment #8 from andreas bittner ---
I think at least my observations on very slow ssh logins (as well as sudo or su
-) can be found due to faulty dbus / systemd-logind.service interactions.
I just found another system which had been updated (zypper up) some days ago or
something.
Slow during ssh client inbound:

Anyone gonna fix another dbus error or systemd-journald.service error here?
Thanks in advance.
