Lucky you...
I haven't seen an appreciable shortening of the boot process after updating my laptop to a release that's full-on systemd. A few seconds less -- maybe -- but it's not as though I was timing my boots. (Does anyone?)
My understanding (please correct me if I'm wrong) was that systemd was intended to benefit the management of virtual machines by reducing boot times for those. Unfortunately for those folks who are /not/ running VMs, they're stuck with systemd anyway.
