I just took a watch:
Laptop (4200 rpm), 1.5 GHz Pentium M, 512 Ram:
46 seconds from grub to working kde (auto login, some karamba apps). It was about 22 seconds until X started to start, so I think I could reach about 30 seconds using an lighter WM
My desktop needs some more time, I need to start net.eth0 and cups there. Didn't use parallel startup on desktop until now (I think I just forgot).
I read some trick here a while ago how to speed up modules loading. It was about putting an "&" somewhere in /etc/init.d/modules to load them at the same time, not one after the other. (the last &)
| Code: | | modprobe -q ${x} ${modargs[${i}]} &>/dev/null & |
Windows:
OK, it is quite fast. But on my desktop for example I have to wait about 10 - 15 additional seconds after Windows seems to have finished booting (no more hour glass) until I can connect to the Internet. KDE instead is ready when It says it is ready, and my internet connection is working a long time before.

It is standard in the current gentoo scripts.
I have tried something deifferent, which can be used to gain some seconds (I gained 5 out of 40)
I had my internet connection and several server startups in the default runlevel. Since X takes about 10 seconds to start on my machine, I wanted that X starts as soon as possible. However, because of some dirty reasons, the X does not start parallely to the other stuff, because it is not really started in the default level, just put into some dummy runlevel by a dirty hack. Now I hacked the following dirty trick.
Therefore I made a new runlevel (called server), and deleted almost all services from the default runlevel and added to this new runlevel. I just let hdparms, local and metalog there. Moreover, and this is important: I added xdm to the new runlevel also. So xdm is contained in both default and server.
And now comes the real hack: I want that this new runlevel starts automatically. So I added the line
at the end of /etc/X11/startDM.sh
Now, if I start my box, then xdm boots before internet and all other services like net.eth0,adsl,postgres,mpd,speechd,..., etc. This can save some "precious" seconds. 
The only drawback I see is that the vt1 will contain some garbage logs instead of the login prompt after booting up, which is not really elegant. However, pressing returns gives a new login prompt.

I played with it some more:
- Moved some of the stuff I don't use every day (like firewire) into modules
- Commented out module dependancy search
- Moved xdm to boot runlevel
New time power-on to kde *completely* up and running: 1:00. 
Not great, but getting there.
Man I still wish I could suspend (to ram preferably)...

If you read the xdm script, you can see that in general it is dangerous to let X start before the getty is up.
On your particular machine, it may be a good idea, but if some service blocks getty, then you may get into trouble: no keyboard in X.
BTW, I have already commented out the depmod stuff, but it did not help much on my box.
I am considering moving some not-important boot stuff into my extra runlevel such as USB startup etc, but am unsure whether it's possible. |

Another ide would be to allow mounting a lot of stuff after X is mounted,
setting hdparms for the other two harddrives may be postponed to a later time (if it is needed at all, I don't know anynmore) |

I would propose openbox. It loads fast as hell, and it's very convincing.
BTW, It seems that the boot-time of KDE also improved a bit 3.2 relative to 3.1.0, but it's just a feeling not supported by any numbers on my side. |

it suprised me that i havent seen it mentioned already, but when comparing bootup times to windows-based operating system, you should bear in mind that windows shows the loginbox/desktop *before* everything has finished starting up. a typical system is generally slow/unusable for quite a few more seconds after that point.
linux will start everything and only then show you the login box.

Mmm, most people seem to neglect this obvious fact! Every Windows-box is practically useless for a couple of seconds after the login...

| Well, one should also bear in mind that most linux boxes are running more services than WinXP boxes. Like sshd, proftpd, nfs, webmin or postgres. |

starting services after login is dangerous on windows - there exists a situation in win2k where you can screw yourself royally
services continue starting during and after login but at login the system saves the last known good config
if that config turns out not to be good then you cannot change the config and its possible to have a non-working config.
So its best to wait a lil while before logging in on win.

But I just did what windows does:
# mkdir -p /etc/svc/bin
/etc/svc/bin/initsvc.sh:
| Code: |
#!/bin/sh
# WARNING: Must be executed with depscan.sh sourced
STARTED_DIR=/var/lib/init.d/started
NET_FILE=/etc/svc/net
AUTO_FILE=/etc/svc/auto
# Execute AUTO stuff
AUTO_FILES=$(< $AUTO_FILE)
for autosvc in $AUTO_FILES
do
/etc/init.d/${autosvc} start
done
if [ ! "$(/bin/ls $STARTED | /bin/grep 'net\.' | /bin/grep -v 'net\.lo')" = "" ]
then
for netsvc in $(< $NET_FILE)
do
/etc/init.d/${netsvc} start
done
fi
|
/etc/init.d/initsvc:
| Code: |
#!/sbin/runscript
start () {
ebegin "Starting service loader"
/etc/svc/bin/initsvc.sh 2>/var/log/svcinit.log 1>/var/log/svcinit.log &
eend
}
stop() {
ebegin "Stopping service loader" #Doesn't need to be stopped, because process has ended anyway
eend
}
|
/etc/svc/auto:
| Code: |
ifplugd
alsasound
apache2
cupsd
gpm
netmount
samba
|
/etc/svc/net: (local because I update my router's port forwarding config)
Then rc-update del all the crap in /etc/runlevels/default, leaving (in my case), metalog, vixie-cron, xdm, xfs and of course, initsvc.
All these services hopefully do not depend on each other, so it works. As for the net part, it needs some fixing, if your DHCP server takes a long time to respond (not so with net.*, but applicable to ifplugd).
Then check your status with /var/log/svcinit.log
This, together with preventing update of module dependencies slashes my startup time by 10 secs, so it is currently at 20s for Gentoo vs 10s for Windows XP. I think this is the best I can go, the rest is all the stuff that cannot be changed (clock, modules, random numbers, loggers, cron).
(Off Topic)
BTW, I have another script that could be of use:
| Code: |
#!/bin/bash
PROGRAM=$0
ACTION=$1
TOPIC=$2
case $ACTION in
-s|list)
ACTION=list
;;
view)

-p|path)

fi
;;
view)
#view logfile
if [ "$zalias" = "$TOPIC" ]; then
sudo less /var/log/$file
exit
fi
;;
path)
if [ "$zalias" = "$TOPIC" ]; then
echo /var/log/$file
exit
fi
;;
*)
# print help
echo 'USAGE: '$PROGRAM' ( list | view ) file

exit
esac
}
for LOG in $(ls -l /var/log | awk '/^-rw/ { print $9}' | sort )

COUNTER=0
for logfile in $FILES_IN_DIR

if [ ! "$(echo $newname | grep '^[0-9][0-9][0-9][0-9]-[0-9][0-9]-[0-9][0-9]-[0-9][0-9]:[0-9][0-9]:[0-9][0-9]$')" = "" ]; then
(( COUNTER++ ))
ALIAS=$DIR$COUNTER
##
elif [ "$newname" = "current" ]; then
ALIAS=$DIR

ALIAS=$DIR-$newname
if [ $newname = $DIR ]; then
ALIAS=$DIR
fi

action $ALIAS $DIR/$logfile
# Usually we have current, log-date, log-date etc (system)
# Now, dates are BAD. Give them numbers instead
# Or we have log.xxx (samba)

done

if you save it as /usr/bin/readlog (0755), you can read your logs by:
$ readlog svcinit
list possible options:
$ readlog list
list options starting with X:
$ readlog list '^X'
etc. |

If you are using dhcp then check the man file for your client, it may start faster with shorter timeout set in the configuration.
I dont find it taking over long to boot my system, although hotplug, dhcp and xfs take their time which bugs me  |

gee, why didn't I think of that? Anyway, as I tend to forget about such things as running manually an updater script, I've hacked it a bit to run modules-update automagically if a file in /etc/modules.d/ is newer than /etc/modules.conf.

| Guys if you want speed use Window Maker or Xfce instead of Kde.....Kde is damn' slow and heavy, I have a G3 800 with 128MB ram and it takes me 40 to 50 seconds to boot into X with WindowMaker.....what if I use KDE?? 2 min. ? I think that some GUI like KDE or the Windows'one are too heavy and full of useless things.... |

thanks for the tip/correction And as a matter of fact one could replace the whole:
| Code: |
NEWMODULES="`/usr/bin/find /etc/modules.d -type f -newer /etc/modules.conf`"
if [ ! "" = "$NEWMODULES" ]
|
with:
| Code: |
if [ -n "`/usr/bin/find /etc/modules.d -type f -newer /etc/modules.conf`" ]
|
without much harm to the readability of the code

Well, I have found that the no "keyboard in X" can be fixed by adding to /etc/X11/gdm/gdm.conf (inittab only configures ttys 1-6). I am using this setting to enable me to do away with the nasty xdm/startDM.sh stuff and create a simpler gdm init script which has the added bonus of not dropping to console view for a second or two inbetween bootsplash progress bar and X. It seems far too simple so I'll probably run into other problems eventually 
Anyway, starting from selecting gentoo grub option to useable* XFCE desktop (via GDM auto-login) in 32 seconds (gdesklet startbar popping up 3 seconds after). Doesn't sound too bad considering the same machine boots from grub to useable* untweaked XP Professional desktop (auto login) in 29 seconds (anti-virus, mbm and various other XP services taking a further 13 seconds to finish loading**).
Not exactly a particularly fair test but still shows that it doesn't have to take 2/3 times as long to boot into linux over windows
* = defined by the time to show desktop and ability to click menu
** = defined by the time taken for first two items to show in tray and the cursor to stop showing hour glass.

There are no official guidelines as to what services should be started based on runlevel. Id take a look at your default runlevels directory and remove the syms there accordingly. (/etc/runlevels/default) If you see sendmail or httpd and dont run a mail or web service your prolly ok to remove those. The syntax to do that is:
rc-update del service default |

My way of doing that is:

if [ -z "${CDBOOT}" ]
if [ /etc/modules.d -nt /etc/modules.conf ] then
ebegin "Calculating module dependencies"
/sbin/modules-update &>/dev/null

And it works fine and fast. Maybe this should be sent as a patch to rcscript developers?
Other things that i have done to make the bootup process faster on my computer:
- Make mount fork itself for paraller mounts:
Replace in /etc/init.d/localmount:: | Code: | | mount -at nocoda,nonfs,noproc,noncpfs,nosmbfs,noshm >/dev/null |
with: | Code: | | mount -aFt nocoda,nonfs,noproc,noncpfs,nosmbfs,noshm >/dev/null |
- Make mounting huge ReiserFS3 partition faster.
It seems that on my computer mounting my home directory which is a 160Gb LVM partition using ReiserFS3 filsystem, takes about 9-10 seconds which is not acceptable if i want to have a quick boot. So i put "noauto" on that partition in fstab and mounted it separately in a background process.
Add in /etc/init.d/localmount: | Code: | | mount /home >/dev/null & |
after | Code: | | eend $? "Some local filesystem failed to mount" |
Warning: Use this patch only if you are sure that your bootup process doesn't need to read/write to /home. And there is no reason to use this if mounting this partition is fast already.
- Do env-update only if necessary.
Replace in /etc/init.d/bootmisc:
| Code: |
if [ -x /sbin/env-update.sh ]
then
ebegin "Updating environment"
/sbin/env-update.sh >/dev/null
eend 0
fi
|
with
| Code: |
if [ -x /sbin/env-update.sh ]
then
if [ /etc/env.d -nt /etc/profile.env ]
then
ebegin "Updating environment"
/sbin/env-update.sh >/dev/null
eend 0
fi
fi
|
- Forced paraller services.
I made a similiar system as xkjyeah did, but just a tad simpler: I removed hotplug, shorewall and rp-pppoe from runlevels. Then i made my own rc-script:
| Code: |
#!/sbin/runscript
depend() {
need net
}
start() {
ebegin "Starting background loading"
/etc/init.d/hotplug start &
# Shorewall before internet connection for safety.
/etc/init.d/shorewall start
/etc/init.d/rp-pppoe start &
}
stop() {
ebegin "Stopping background loader"
}
|
With this i put hotplug to background, load firewall before i connect to the internet and then connect to the internet at the background. Setting this kind of script is highly subjectible depending on your configuration, but this rc-script fastens my bootup a lot. For some reason RC_PARALLEL_STARTUP="yes" didn't help as much as manually forcing backgrounding of these scripts.
- Removing boot filesystem checks.
ReiserFS FAQ told to use 0 as pass value in /etc/fstab on ReiserFS partitions so i did it, and it made it somewhat faster because i have some big ReiserFS partitions.
Conclusion:
With these optimizations my Gentoo/Linux bootup time went from 1m20s to 20-30s which is quite a big leap. Setting up LVM takes the longest time on my bootup process at the moment and i have no idea how to make that faster, propably can't because it only runs tools that is provided by the LVM package.
Maybe we should make a thread about these tweaks in "Documentation. Tips & Tricks" |

That's rather strange, it takes me about 30 seconds to go from grub to being inside gnome, and prolly 40-45 seconds before windows xp is actually usable (sure the screen comes up, but it needs to finish loading the services before you can even open firefox).
Plus watching the kernel tell you what it's doing is more interesting to watch than that low res winxp loading screen. |

I removed module support alltogether from my kernel and it seems to boot up uber fast, and the cool thing is firehol still seems to work
I can basically boot up and start fluxbox in under a minute,
which is pretty good considering how old my computer is
