The machine is an iocage jail host, all jails with VNET.
The problem is: network performance in the jails (not on the host!) is
abysmal
with the second setup. Not consistently so, everything *seems* to work
but e.g. a customer complained that checking out a project from github
happend at 15k/s … that’s when we started to investigate.
[...]
*Any* idea what might be going on here? We use VNET all the same on all
the
hosts and it is still labelled „experimental", yes. But all the parts
that
make up the different setups - bridge(4), vlan(4) - have been in
FreeBSD
for ages. I’m just combining features orthogonally like every good
sysadmin ;-)
If someone is willing to do some investigation, I think I can provide a
test
system and remote access …
This sounds familiar to me, please have a look at the following two
threads:

https://lists.freebsd.org/pipermail/freebsd-net/2017-December/049470.html
If your hosts run on cloud infrastructure odds are that the mentioned
settings will work in your case.
Regards,
Michael
