If you want fast boot times go to a solid state drive. My HP laptop with 
an AMD quad core and 8 gigs of ram boots up 14.04 in almost no time. 
That point when the splash screen shows each step in sequence as they 
load. All light up at once and your looking at the desktop. You go from 
the Grub boot select screen [ the laptop is dual booted ] to the desktop 
in less time than your time to login screen.
