I just thought of another relevant setting that my normal context has but that the RPi4B snapshot does not have (by default) and you might not have: use of noatime (or analogous for ZFS) The default /etc/fstab for the snapshot: # more /ets/fstab # Custom /etc/fstab for FreeBSD embedded images /dev/ufs/rootfs / ufs rw 1 1 /dev/msdosfs/EFI /boot/efi msdosfs rw,noatime 0 0 tmpfs /tmp tmpfs rw,mode=1777 0 0 /dev/label/growfs_swap none swap sw 0 0 Keeping access times updated causes lots of extra I/O activity. My future snapshot testing will likely mostly be with: # more /etc/fstab # Custom /etc/fstab for FreeBSD embedded images /dev/ufs/rootfs / ufs rw,noatime 1 1 /dev/msdosfs/EFI /boot/efi msdosfs rw,noatime 0 0 tmpfs /tmp tmpfs rw,mode=1777 0 0 /dev/label/growfs_swap none swap sw 0 0 === Mark Millard marklmi at yahoo.com
