39 seconds normal boot time on my system with modprobe of all modules.
Now a measurement without modprobe:
# mkinitrd -f $(/sbin/lsmod |while read a b; do echo --preload
$a;done|fgrep -v Module) /boot/initrd-$(uname -r).img $(uname -r)
initrd now loads all used modules and we can disable modprobe:
# mv /etc/udev/rules.d/80-drivers.rules
/etc/udev/rules.d/80-drivers.rules.bak
Now the boot time is 36 seconds.
So, you can shave off a maximum of 3s with modprobe optimization on my
system. Also a "small" performance boost.
Also very interesting: if I turn on modprobe again, it takes 38 seconds.
So 2 seconds for already loaded / non existent modules.
