FWIW, here are my times for my fastest desktop (athlon64 4000+) and
my latest (via C7D 1.5GHz, using an old LFS-6.1 system that was on
the disk, static ip, no X). I don't have a stopwatch anymore, and
my watch has a rotating second hand, so these times are only
accurate to a couple of seconds. Also, I care about the time it
takes to get to a bootloader prompt because it is part of the
power-up experience. I restarted the timings from when I hit
<enter> after selecting which kernel/system. All in seconds.
a64 4000+ c7
power on 0 0
bootloader prompt 14 16
select the kernel/system 0 0
init starts 7 20
console prompt 54
gdm prompt 45
On the C7, ntp takes about 19 seconds, nothing else stood out.
On the athlon64, dhcp took about 5 seconds, ntp about 14 seconds,
and X itself is dog slow to start. Might be the particular driver
or the particular card.
