Since updating to FreeBSD 11.2, I notice a significant delay of 2 to 3 seconds when logging-in from my Mac via ssh to my FreeBSD boxes in the LAN, and this is independent on system hardware, and processor speed, it happens with either of Atom dual core 1.6 GHz, Core i7, quad core 4 GHz and ARMv6 1 GHz of a BBB. In all cases I got in sshd_config(5) UseDNS no.
So, what the hell is sshd doing behind my back for 2 to 3 seconds before responding? 2 seconds are worth of 10 giga-instructions on modern processors, and thinking about this, I become a little bit nervous.
