Not my experience at all.
I actually timed systemd vs non-systemd boot time on my desktop. Non-systemd won by a significant margin.
The systemd people gave me a reasonable response: systemd is faster because it start services in parallel. This is helpful when you run a lot of services - like some servers. On a desktop, where are not running so many services, systemd can be slower than non-systemd.
I do not have the specifics of my test available right now. But I do remember that non-systemd booted faster.
Ubuntu 10.4 - just before Gnome3 was awesome. It is sad they ruined such a great distro.
