[SOLVED] Boot speed

corsakh · 2009-11-13 08:24:12

Sup,

I have just installed the system. I heard that Arch is supposed to boot very quickly, but after installing just Gnome it was actually starting slower than fully bloated Ubuntu. I changed the daemons a little, and its now significantly faster but still over 30 seconds (Ubuntu on minimal install takes about 25 seconds on my machine).

This is the order I am using:

@gdm @syslog-ng @alsa @network hal @crond @fam

Its probably totally wrong. What can I improve and what are other effective methods to speed the boot up?

A few thoughts from my end:
Remove gdm from daemons and don't background syslog-ng. Put dbus and then hal after syslog-ng. Remove fam and install gamin. If you want gdm to start automatically edit /etc/inittab and change to init5 and then x session at the bottom to gdm instead of xdm.

I backup sHyLoCk thoughts with the minor change that, because HAL launches dbus you just need to put HAL and preferably right after syslog-ng

Can I background hal?

Usually: No. It is responsible for proper hardware setup and must have finished its work before othe modules can use the hardware.

Check out the quick-init script in AUR

corsakh · 2009-11-14 13:09:16

Ok, good news: I boot in 15 seconds
Bad news: Boot up crashes 3 out of 4 times

Ok, a little preamble. I have two disks, one with windows, one with arch. For some reason, different programs at different times may read them as different devices, ie one program would read disk 1 as sda, another would read it as sdb. So when I boot up and it checks the file systems, half the time it reads it correctly and half the time not - every time it does not read it correctly, I crash. So I changed fstab by UUID and it works great, no crashes. Now quick init for some reason does not like this UUID and at the end I receive a noswap message saying dev with this swap UUID can not be found. Ok, so I go to fstab and change UUID to /dev/ format, and the quick init works. But now I crash half the time when the file system is checked. And half the time at the end of the boot, before the graphical interface starts. So effectively I crash 75% of the time Can I use fstab with UUID and quick init at the same time? Should I replace /dev/ format with UUID= format in that paste fragment?

sHyLoCk · 2009-11-14 13:27:23

You must ask adriano. Come to the quick init discussion. But anyway it is no way related to Arch since its a 3rd party script.

just curious
whats the most efficient order for my daemons ?

syslog-ng network netfs crond hal @alsa @sshd @httpd @fail2ban @mysqld @svnserve @cups

Just a thought:

syslog-ng hal @crond @network @netfs @sshd @httpd @fail2ban @mysqld @svnserve @alsa @cups

oh god. i tried the quick init script and it broke something
so i uninstalled, and replaced my original inittab. it and now i can't boot into runlevel5 anymore.
here is my inittab

# /etc/inittab
#

#  Runlevels:
#    0    Halt
#    1(S)       Single-user
#    2    Not used
#    3    Multi-user
#    4    Not used
#    5    X11
#    6    Reboot

## Only one of the following two lines can be uncommented!
# Boot to console
#id:3:initdefault:
# Boot to X11
id:5:initdefault:

rc::sysinit:/etc/rc.sysinit
rs:S1:wait:/etc/rc.single
rm:2345:wait:/etc/rc.multi
rh:06:wait:/etc/rc.shutdown
su:S:wait:/sbin/sulogin -p

# -8 options fixes umlauts problem on login
c1:2345:respawn:/sbin/agetty -8 38400 tty1 linux
c2:2345:respawn:/sbin/agetty -8 38400 tty2 linux

c5:2345:respawn:/sbin/agetty -8 38400 tty5 linux
c6:2345:respawn:/sbin/agetty -8 38400 tty6 linux

ca::ctrlaltdel:/sbin/shutdown -t3 -r now

# Example lines for starting a login manager
x:5:respawn:/usr/bin/xdm -nodaemon
#x:5:respawn:/usr/sbin/gdm -nodaemon
#x:5:respawn:/usr/bin/kdm -nodaemon
#x:5:respawn:/usr/bin/slim >& /dev/null

# End of file

if i login on runlevel 3 and do startx ... everything starts normally .

i have id:5:initdefault uncommented in inittab

Copy paste your inittab here.

i edited my post above

i tried to catch some of the output from the boot process but it was going too fast. it said something like failed run level 5 reverting to run level 3
i don't know if this helps

is there a way to pause the output?

And who will change this line ?

murfMan · 2009-11-14 15:41:40

LOL

thanks man.

corsakh · 2009-11-14 21:07:28

I think its working fine now after setting normal partitions by UUID and spaw by /dev/ in fstab.

12 seconds, much better.

12 seconds from grub to ??? (using bootchartd?)

please consider reading this post: http://bbs.archlinux.org/viewtopic.php? … 05#p657505

Is it safe to background network?

I have a SSD drive and my boot process is very fast, the only thing that takes forever ist network. When I don't have my ethernet cable plugged and only wlan is up, it takes even longer.
I also have privoxy in my daemon list, so I'm not sure.

I avoided that issue by using netcfg and removing network from the daemon list altogether. See netcfg in the wiki for details.
