I don't know much about the boot profiler, but likely, it can
influence the time between kernel loading and starting X11 only. On
my machine, a fairly recent dual core desktop, most time is used on
the other parts: the vendor's BIOS screen, Grub waiting a few seconds
for possible user input, X11 and Gnome launching.
Nevertheless, a gain of a few seconds is great, considering the boot
sequence (hopefully) remains stable and it's a gain on each of
millions of computers.
