Kubuntu host, VirtualBox guest, pkg 2.2.2, 15.0-PRERELEASE.
Slow physical storage for the virtual drive: a mobile HDD on USB.
bsdinstall, ZFS, 8 G swap, pkgbase, all components, then:
|pkg install --glob 'FreeBSD-kernel-generic-nodebug*'|
= 568 base packages.
vm.pageout_oom_seq=120
After base installation: 1 G memory given to the guest, GENERIC-NODEBUG,
dmesg showed 932 MB avail.
Fetch then install some FreeBSD-ports packages. From

Then, at ttyv3:
htop
at ttyv2:
tail -f -n 0 /var/log/messages
at ttyv1:
|/usr/bin/time -h pkg upgrade -fqUy|
= a quiet forced upgrade of all packages, complete in 17 minutes, 2.62
seconds.

With htop, I observed swap usage sometimes above 2 G. Never 3 or more,
although I did not watch constantly.
