I have to say that it is super fast to boot up with systemd. Maybe 2-3 seconds to boot to my Ubuntu desktop (excluding bios time.) I do use an SSD however.

  On embedded devices in the SheevaPlug family, it's a bit slower than the old init, presumably because it's doing a lot more stuff (and the OS is either on slow flash or a slow USB-to-SD card interface). It doesn't seem to scale down to small systems very well. I do like the colors, though.

    systemd has boot profiling functionality, you might want to check out which part is slow.

      There's always lots of text flying by on the console; it might not be traceable to one single slow part.

        Try "systemd-analyze plot >boot.svg" and it will produce a nice svg graph of how much time each step takes.

          I never knew that.. thanks, that is very interesting..

          Also check out the other subcommands. For example, to find out why a certain service is taking long to start up, "systemd-analyze critical-chain $service"

    systemd is slow on my embedded devices booting from flash too.

      On slow storage systemd has some problems. Afair you can configure it to not be as parallel. That ought to help.

        I could have sworn that i read a notice a year or two ago that they pulled out the readahead code because it had not been maintained in a while and all the devs were using SSDs.

  I have a 2-second boot from grub to login with plain-old sysvinit. What's remarkable about systemd? And perhaps more relevant, given that BIOS boot times are still above 10 seconds (and minutes on servers), who cares?
