It has been a while since I synchronized but I've never historically had
problems with the USB3 Ethernet dongle automatic operation. But my
context is DHCP with /etc/r.conf having:

ifconfig_DEFAULT="DHCP inet6 accept_rtadv"

I think Bob P. may use static addressing on his RPI*'s but that he does
not have a RPi5 (any variant).

Once I manually page the interface down/up after

A prebuilt main normally has a debug world and a debug kernel. Expect
buildworld and buildkernel to take notably longer than if a non-debug
world is used, for example. World looks to be the bigger time issue,
through both the debug kernel also leads to more time.

Also: Do you have a fan/heatsink? If you have a fan, is it operating?

Depending on the details, you might have temperature issues for such
activities as buildworld, buildkernel, poudriere bulk (or other forms of
port/package building). That too can slow things down.
