And you always should keep in mind: 100% of all commonly used benchmarks are just wrong. Without a deeper understanding and an 'active benchmarking' approach you will always end up with misleading results and draw the wrong conclusions.
A great source of information is provided by one of my personal heroes:

# Backup old working boot.cmd and boot.scr files
$ cp /boot/boot.cmd /boot/boot.cmd.nosystemd
$ cp /boot/boot.cmd /boot/boot.scr.nosystemd
# Edit boot.cmd to insert 'init=/bin/systemd' at the first arg of bootargs
$ nano /boot/boot.cmd
setenv bootargs "init=/bin/systemd console=tty1 (...)"
# Recompile boot script
$ mkimage -C none -A arm -T script -d /boot/boot.cmd /boot/boot.scr
# Reboot
reboot
For me that worked
Maybe we could add this in the main docs http://www.armbian.com/documentation/ ?
