> 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.
