Disabling services you don't need can speed up boot, and is much
easier in the long run than compiling a customized kernel because you
only have to do it once.
I run a self-compiled kernel (3.7.4) on my F17 box, I've removed all the
modules I don't need. I did it because I run Gnome on a 1 GB box and
need all the memory I can get. I also don't run any services except
dbus. Gnome still loads a crapload of stuff that I can't remove. My idle
memory usage (in Gnome) is 130 MB.
It boots at exactly the same speed as the Fedora kernel. Disable all the
services that you can, and things will boot quicker, but not that much
quicker. Systemd does a great job of running startup jobs in parallel.
Because I have an encrypted home, boot time doesn't mean a lot, it takes
me longer to type the luks password.
