I've got it down to about 4 1/2 hrs for the buildworld/buildkernel steps. But this is after all this has been done: for stable/13: 1. configuration and use of devel/ccache-static 2. clocking to 2.0 GHz with the following config.txt: [...] % less /boot/msdos/config.txt arm_control=0x200 dtparam=audio=on,i2c_arm=on,spi=on dtoverlay=mmc dtoverlay=pwm dtoverlay=disable-bt device_tree_address=0x4000 kernel=u-boot.bin over_voltage=6 arm_freq=2000 sdram_freq_min=3200 *make SURE you have good cooling!!!!!* I have a flirc rpi4 case on this one. 3. /usr/obj /usr/src and /var/cache/ccache on zfs on usb3-connected spinning rust 4. /tmp as tmpfs (512mb) 5. make -j6 buildworld && make -j6 buildkernel (after make -j10 cleanworld && make -j10 cleandir && make -j10 clean) 6. having *already built* a new world and kernel and installed it all and rebooted, which had been built with the following /etc/src.conf : [...] WITH_MALLOC_PRODUCTION= WITHOUT_DEBUG_FILES= WITH_CCACHE_BUILD= WITH_OPENSSL_KTLS= WITHOUT_APM= WITHOUT_ASSERT_DEBUG= WITHOUT_BLUETOOTH= WITHOUT_CUSE= WITHOUT_DICT= WITHOUT_DMAGENT= WITHOUT_FLOPPY= WITHOUT_FREEBSD_UPDATE= WITHOUT_HAST= WITHOUT_IPFILTER= WITHOUT_IPFW= WITHOUT_ISCSI= WITHOUT_KERNEL_SYMBOLS= WITHOUT_LLVM_TARGET_ALL= WITH_LLVM_TARGET_AARCH64= WITH_LLVM_TARGET_ARM= WITHOUT_LPR= WITHOUT_NDIS= WITHOUT_NETGRAPH= WITHOUT_NIS= WITHOUT_OFED= WITHOUT_PORTSNAP= WITHOUT_PPP= WITHOUT_RADIUS_SUPPORT= WITH_RATELIMIT= WITHOUT_RBOOTD= WITHOUT_ROUTED= WITH_SORT_THREADS= WITH_SVN= WITHOUT_TALK= WITHOUT_TESTS= WITHOUT_TFTP= WITHOUT_UNBOUND= # CFLAGS.clang+= -mcpu=cortex-a72 CXXFLAGS.clang+= -mcpu=cortex-a72 CPPFLAGS.clang+= -mcpu=cortex-a72 ACFLAGS.arm64cpuid.S+= -mcpu=cortex-a72+crypto ACFLAGS.aesv8-armx.S+= -mcpu=cortex-a72+crypto ACFLAGS.ghashv8-armx.S+= -mcpu=cortex-a72+crypto (and afterwards, make check-old (then) yes | make delete-old then yes| make delete-old-libs) then 7. with the following in /etc/sysctl.conf : vfs.read_max=128 With regard to building ports (I use poudriere-devel) with jobs=4 I see the following build times for the largest five ports built subsequently: rust-1.51.0 took 7hrs 46mins doxygen-1.9.1,2 took 1hr 36mins texlive-texmf-20150523_4 took 1hr 36mins llvm10-10.0.1_5 took 1hr 4mins binutils-2.33.1_4,1 took 57mins 37s The poudriere jail instance for this rpi4 uses the same /usr/src as what has built the OS. This means it was built with the same /etc/src.conf parameters. My other rpi4 (runs main/14, currently I'm testing it) will clock to 2.1GHz. I've not thoroughly tested buildtimes there yet. I forgot to mention both my stable/13 rpi4 and main/14rpi4 run powerd with these lines in /etc/rc.conf: powerd_enable="YES" powerd_flags="-r 1" -- J.
