Well, there are a number of separate optimizations in systemd:

1. Delayed loading of services (or even not loading them at all, if not
   needed. E.g.: don't load CUPS if nobody needs it.

2. Paralelized loading of services (though there have been other
   implemtnations of that. SuSE has had that for years: insserv).

3. Rewriting some scripts in C. Also note that udev has been going
   through this for quite some time as well.

4. A nice facility to get the timing information and show where the
   actual bottlenecks are.
