2 days of tweaking for a faster boot time

Duologic · 2009-01-07 16:29:36

2 days of tweaking for a faster boot time
Why: just because I can, for other people to see what is possible with (Arch)linux.
Grub to agetty in 13s (coming from 24s)

Before: (after fresh install)
>Bootchart taken offline! 24s boot
After: (2 days of tweaking)
>Bootchart taken offline! 13s boot

Commenting stuff in /etc/inittab
wait -> once
lesser agetty's
no login manager

# /etc/inittab

id:3:initdefault:

rc::sysinit:/etc/rc.sysinit
rs:S1:once:/etc/rc.single
rm:2345:once:/etc/rc.multi
rh:06:once:/etc/rc.shutdown

# End of file

Rough cleaning of /etc/rc.sysinit
Stripping out LVM, RAID, Encrypted
Defaulting hwclock behavior
Fine tuning /etc/rc.sysinit
Adding a lot of ampersands to send stuff to the background
Activate '/sbin/udevadm trigger' earlier
Commenting Module depencies
Including default behavior (LOCALE, KEYMAP, HOSTNAME)

good work. what does changing wait -> once do?

Duologic · 2009-01-07 16:43:41

I'll try anything too speed up boot for my system, and I found that hack here: http://kmandla.wordpress.com/2007/01/28 … n-inittab/
I didn't pay much attention to inittab.

Zariel · 2009-01-07 17:09:20

How do you login?

fwojciec · 2009-01-07 17:10:13

Amount of seconds used to achieve faster boot time: 60*60*24*2 = 172800
Amount of seconds saved each boot: 11

Great! Now you just need to boot your computer 15709 times to make up the time

EDIT: Nice writeup, by the way -- I'm sure people will find it useful.

That's 43 years if you turn on your computer once a day.

Duologic · 2009-01-07 17:27:32

Zariel: With agetty and I got 'xinit &' in ~/.bash_profile to load X directly. Maybe I will add it to the wiki, but that takes more work than just posting it here.

fwojciec: 15702 times divided by the people who use this to speed up there boot time, and actualy I didn't spend the full two days to do this, just thought it sounded nice (check the dates on the bootcharts).

I've said it before, and I'll say it again: time used when you can spare it to save time when you can't isn't wasted, even if you end up using more overall than you actually save.

A great post like this and then without a single 'edit'. Nice job!

Duologic · 2009-01-08 00:00:57

I've got my secrets on doing that

vh22 · 2009-01-08 00:07:34

Nice post! I was doing something similar yesterday . I found that if I take out all the kernel hooks except base in mkinitcpio.conf and just load all the modules I need manually, I can save time. I went down from about 35 seconds to about 15 seconds on a virtual machine.

Duologic · 2009-01-08 00:14:08

That sounds great, I'm planning to do the same in the near future to go below 10 seconds.

In theory if I would have done that in first place and count 20 seconds of my first boot, I'm booting in $-) like 4 seconds.
I gues that's to good to be true...

vh22 · 2009-01-08 00:18:59

It wasn't that alone that brought the boot down 20 seconds. It was almost everything you did plus that.

And a 4 second boot sounds great. i have a laptop and suspend is iffy, unfortunately.

you could also kick some HOOKS:
add to MODULES array

MODULES="ahci <your fst here - eg: ext3>"

(though i think you also need sd-mod - not sure)
and omit sata (you have already ahci so you do not even need sata) and filesystems.
if you do not have an usb keyborard you can also drop usbinput.
then you HOOKS look like:

HOOKS="base udev"

you could also omit udev, but if you use persistent partition naming (which is very useful), you'll need that.
however, the hooks don't take so much time. you'll save perhaps only one second or so.

Very impressive, I dream of a 13 second boot time.

Army · 2009-01-08 11:13:53

Nice! I'll definitely take a closer look at this guide, maybe I'll try it out.

iBertus · 2009-01-08 12:11:40

All of this doesn't help me any since my board takes ~45-60 seconds in BIOS before passing on to GRUB. This board (Intel D5400XS) is the slowest booting board that I've ever had.

Still, keep up the good work.

Ouuch. That sucks.

Yeah, I'm happy with the system, but wish the boot performance were better. The worst part is that this machine is an energy whore and so I pretty much have to shutdown when I step away from the computer for any length. I'd feel bad about drawing ~500W from the mains when it can be avoided.

however, the hooks don't take so much time. you'll save perhaps only one second or so.

I got as far as this now, can you refer me to some documentation that helps me with non-persistent naming. I would love to try it out, but can't find good documentation.

I did needed the sd-mod, forgot to make a copy of a working kernel image and didn't got further than ramfs$. I got to save my installation with the install USB. ( I'll be writing another topic on that later, think it would be interesting for people that forget to make backups :-D )

I need to do some of this to get my 12 second bootchart lower

My cold boot to getty is ~30s, that isn't too bad I guess. I added some & to rc.sysinit and moved udev trigger up the rc.sysinit some.

I havn't tried the /lib/udev/load-modules.sh trick yet, nor the inittab 'once'.

Great write up. Would you mind if I put this in the wiki? Under your name of course.
