"When Speedboot is being used, only necessary services
will boot prior to starting the graphical display manager, while
all other tasks will start-up after that. These minimal services
include ACPI, D-Bus, HAL, and Syslog. There are also some other
changes involved such as not running many actions with initscripts
and disabling readahead when in this mode. Of course, Mandriva's
Speedboot truly isn't making the system faster as a whole, but is
just taking time away prior to the user being able to log-in and
push that work until after the log-in process or the graphical
display manager is running. Until enabled by default, Speedboot can
be used on the beta for Mandriva 2009.1 and later by adding
"speedboot" to the GRUB's kernel configuration.
"We tested out Speedboot on the Mandriva 2009.1 beta with the
same Intel netbook we used for other recent Linux boot articles.
This netbook is the Samsung NC10 with an Intel Atom N270 CPU, 2GB
of DDR2 memory, and an OCZ Core Series V2 SSD. Some of the key
package versions in Mandriva 2009.1 beta include the Linux 2.6.28
kernel, GNOME 2.25.90, X Server 1.6.0 RC 2, xf86-video-intel 2.6.1,
Mesa 7.3, and we were using the EXT3 file-system."
