I do have to admit that I am lost here, and that I cannot think

severs has been some weeks ago. Ever since I did upgrade FreeBSD
11.1-STABLE, and I did move my infrastructure from bare metal to
cloud, thus I cannot test anymore if my old servers would have shown
that performance issue in the meantime.
Thus any feedback is highly recommended!
Can you try turning off TSO? (`ifconfig $ifname -tso`)
There have been issues with pf and TSO checksums, which looked a lot
like this (i.e. bad TCP performance). Those problems should be fixed,
but this is easy to test.
I did try it, but without success.
Hmm. I’ve got no ideas at the moment. I run a very similar setup
(although on CURRENT), and see no performance issues from my jails.
Can you test a performance test without pf? Perhaps from the local LAN
for example? That should help narrow it down a bit, at least.
