For me startup is very quick with systemd, it's the shutdown that's slow. About three minutes to shutdown.
Mine is actually slower but not by a huge amount, somewhere between 5 and 10%, varying from one boot to the next. The shutdown is either quite a bit faster, enough so that I worry whether things are being shut down correctly, or a whole lot slower, with no rhyme or reason as to why or which one I'll get on any particular shutdown. Systemd's "improved" logging system is, of course, no use in figuring it out.
