Fedora too has been using it since probably the same time as Arch. (I don't know about other distros, however). If managed properly 'systemd' can really speed up the 'boot time'. Read this to learn what can be done in fedora to speed up boot times. There are mixed views out there about which is better, 'init' or 'systemd'. Personally, I can't tell which is better overall, however I feel that 'systemd' is a bit faster. My two cents...

I am glad Ubuntu will eventually adopt systemd as its default init system. I find it quite cumbersome to enable/disable system services with Upstart, as I have to go to /etc/init and rename unneeded services to <service>.disabled. It's really easy to use the 'service <service> stop|start|etc command to stop and start them, but there is no obvious way to disable services so that they don't start at boot time. systemd is great when it comes to managing services and run levels. I also enjoy the journald feature of systemd, which allows you to view the system log with the journalctl -f command. I have noticed that a systemd reduces bootup time by a significant amount.

I don't suppose any one has installed bootchart and done some comparisons.

And how to be sure that ubuntu 14.10 uses systemd or upstart for boot ? How to switch between these two ? Because as i saw, all systemd packages are already installed by default.
to boot with systemd in utopic is simple boot, edit the boot line - find the 'linux line and add init=/lib/systemd/systemd then F10 will boot with systemd instead of upstart when you're sure all is ok you can edit grub and add it there GRUB_CMDLINE_LINUX_DEFAULT="quiet splash init=/lib/systemd/systemd " don't forget to update grub after changing that
Greetings, /proc/1/comm will tell you what system you are running. Init = Upstart, systemd = systemd systemctl list-units will give you more info if its systemd. Regarding boot time I am getting 80sec for both systems running a stop watch from a cold start kernel selection to the Unity Task Bar. I don't see how it is helpfull to measure to the hand-off when the GUI isn't available. Timing it to the GUI takes the same time on my system.
Greetings, Previous post aside, I prefer the systemd. My system seems much smoother now than with upstart. With systemd Ubuntu/Unity compatibility in heavy development it keeps getting even better. The word "out there" is that it won't be default until 16.04 but I can't see a reason to use anything else now. After all systemd isn't new it has been used by most of the Linux mainstream community for a few years.
And bootchart is kind of broken i think, my system boots in 10 seconds, but bootchart generated picture shows me over a minute
