This was using over_voltage=3D6 and arm_freq=3D2000 via
config.txt . The environment is (mostly) based on
head -r360311 . EFI/BOOT/BOOTAA64.EFI ( loader.efi )
was more recent. A USB3 Ethernet is in use because
the built-in Ethernet does not show up in FreeBSD.
( /dev/mmcsd0 does not show up either. ) The RPi4
has heatsinks and a fan and was using a 5.1V 3.5A
power supply.
I deleted the prior contents of the build tree first.
. . .
make[1]: "/usr/src/Makefile.inc1" line 323: SYSTEM_COMPILER: Determined =
that CC=3Dcc matches the source tree. Not bootstrapping a =
cross-compiler.
make[1]: "/usr/src/Makefile.inc1" line 328: SYSTEM_LINKER: Determined =
that LD=3Dld matches the source tree. Not bootstrapping a cross-linker.

>>> World built in 43050 seconds, ncpu: 4, make -j4
. . .
>>> Kernel(s) GENERIC-NODBG built in 2768 seconds, ncpu: 4, make -j4
So a little under 12 hours for buildworld and somewhat under 50
minutes for buildkernel. So, somewhat under 13 hours overall when
not needing to build a bootstrap compiler or linker. But my
selections of what/how to build are somewhat unusual. For
reference:

I currently use the same media with a Rock64 and
currently choose to tune for that CortexA53 context
instead of for CortexA72. (Both are -march=3Darmv8-a
and so are compatible.)
For reference, my odd variation of top
reported:
2104Mi MaxObsActive
661004Ki MaxObsWired
2628Mi MaxObs(Act+Wir)
"Obs" is short for "Observed".
