I got Ziga's bootcharts working for gentoo, sent patches to Ziga and he merged them.
To install, emerge baselayout 1.11.6-r1 and sysstat, download bootchart from cvs, run install.sh, reboot. After you reboot log in as root and run /etc/bootchart/bootlog stop. Then go to Ziga's page, put the gzipped logs there and save the png or svg.
Here are some charts that I have produced with Ziga's help. You can emerge librsvg and view them with rsvg-view
this chart is the default boot sequence
this chart is the default boot sequence with RC_PARALLEL_STARTUP="yes"
this chart is with bug 69854
this chart is with bug 69854, bug 55329 and bug 70689.
this chart is with bug 69854, bug 55329 and bug 70689. Removed coldplug and alsa is on default instead of boot
Enjoy.  |

I emerged baselayout-1.11.6-r1, tried to apply your modules-update patch and got a reject on /etc/init.d/modules:
| Code: | /etc/init.d/modules.rej
***************
*** 81,91 ****
return 1
fi
- if [ -z "${CDBOOT}" ] && touch /etc/modules.conf 2> /dev/null
then
- ebegin "Calculating module dependencies"
/sbin/modules-update &>/dev/null
- eend $? "Failed to calculate module dependencies"
fi
if [ -f /etc/modules.autoload -a ! -L /etc/modules.autoload ]
--- 81,91 ----
return 1
fi
+ if [ -z "${CDBOOT}" ] 2> /dev/null
then
+ #ebegin "Calculating module dependencies"
/sbin/modules-update &>/dev/null
+ #eend $? "Failed to calculate module dependencies"
fi
if [ -f /etc/modules.autoload -a ! -L /etc/modules.autoload ]
|
Can someone post the patched /etc/init.d/modules?
edit: I'm an idiot ^^ I had forgot etc-update, now it works

From grub to (console-)login: 17 seconds.
Newcastle 3200+.
Edit: I use parallel boot and have disabled module calculating.

i've skimmed through this and other threads related to speeding boot time, and still can't see what i'm doing wrong (i've removed everything unnecessary with rc-update, and i'm already starting in parallel, prelinking, etc.). but i know i'm doing something wrong, because my slackware install booted MUCH faster than gentoo.
with the same kernel (minus gentoo patches, but with the bootsplash patch and with the same modules compiled in) and, more importantly, the same services (mostly essential stuff, plus a few extras like cups): 13 seconds from grub to login in slackware, 32 seconds in gentoo. gentoo's startup cannot possibly be that much clumsier, so i'm assuming the extra 19 seconds is due to my own ignorance...but it's annoying that something i could do in a few minutes on slackware (i.e. comment out unnecessary sections of boot scripts to speed things up) after just a few hours of experience with that distro still has me stumped in gentoo after more than a year. is it just me, or is slackware's boot process easier to follow?
anyway, i suppose it was good (if slightly demoralising) to see how much faster slackware was...i thought my lovingly crafted gentoo setup was reasonably lean and efficient, but obviously not. now i can work on getting it up to speed.  |

Can you apply the patches safely to baselayout 1.12.0_pre11-r3?

oh yeah, i still have this memory of my early slackware experience - breath-taking. and i've been demoralised too because my very much customised gentoo didn't catch up. i gave up trying when i could suspend-to-ram my laptop - and ever since i didn't care. but you just woke up a sleeping goal

emerge sys-apps/initng
It's a faster but experimental alternative to sysvinit. All you have to do is:
1. emerge it
2. change your grub/lilo conf to use initng instead of sysvinit (grub users add "init=/sbin/initng" to the end of their kernel line)
3. use ng-update (instead of rc-update, same syntax) to set which services/daemons/whatever to start at boot - the defaults probably aren't what you want

thanks a lot for that link. i'll definitely try it out - after some test my server is waiting:

I recompiled some apps with -Os instead of -O2 or -O3, seems to improve a bit startup time.
The app I recompiled are: acpid, anacron, cups, dbus, portmap, fam, fdm, vixie-cron
Anything that needs to start fast, instead of to run fast, is better compiled with -Os
I also moved kdm earlier in the boot, and coldplug later, managing almost all my hardware with modules autoload.

How did you did that? And it's safe (wait for coldplug loading before to start kde -even with autologin-)?

i tried initng on my amd64 box (masked from portage). could boot several times, but then resulted in a reocurring kernel panic upon loading syslog-ng. couldn't boot with sysvinit no more neither. used a livecd to chroot into my system, un-merged initng AND syslog-ng and rebuilt syslog-ng. i'll wait some time before i try it out again on a amd64 system.

i've initng installed since 0.3.x on my amd64 system and never had such problems |

how much is the gain you see in the boot times? |

| Never thought that the parallel boot process brought so much performance. I have a basic desktop system with additional services like Apache-2, fnfxd, dhcp on ethernet, etc. RC_PARALLEL_STARTUP="yes" shortened boot time to roughly 60% of the normal time. Here are two charts made with bootchartd-0.8: http://weblog.frexx.de/2006/03/01/gentoo-linux-parallel-startup/ |

I use an old IBM Thinkpad 570, with a 333mhz P2 cpu with 128megs of ram my computer boots less than 30 seconds mainly due to compiling the kernel yourself. Another way to startup really fast is by going to hibernation, sure suspend to ram is much more efficiant because it doesn't use any battery life, but hibernation is not buggy like suspend to ram and uses very little battery life. If i use hibernation I can get to the console in 3 seconds, but if i hibernated in fluxbox it'll take 5 seconds. Just thought I should put in my two cents.

Actually, for suspend to ram, you don't need the software suspend patches. As root, just do
| Code: | | echo -n mem > /sys/power/state |
(you might have to enable some acpi stuff for that if you haven't already). I edited /etc/acpi/defaults.sh so that this is done whenever I press the power button. This actually works better and much faster (like 2 seconds) on my machine than suspend2!
| Quote: | | you start exactly where you left. it's the same functionaly as "hibernate" in windows. |
Suspending to disc is the other thing. Also quite useful but might need quite some experimenting to get the configuration right. |

Hi, nice thread!
I am wondering if you people could help me. The problem is that the boot process takes a very long time AFTER the service Local has started.
Service Local itself does not start anything, /etc/conf.d/local.start is empty, I don´t start anything with it. So it is not the Local service that holds up the boot, but something else that comes after that. And that something else is the mystery here. I have nothing else starting after that, at least there is no other output after the "Service local started", it just takes almost 10 seconds from there to get to login prompt. I do have xorg-server installed, but it is not started automatically, I start it with "startx" if needed.
This is happens in HTPC/DVR (Digital Video Recorder) machine, so I am VERY interested to shave that extra ten seconds of. Can you pretty please help me in this? |

| Just a shot into the dark but maybe you're starting services in parallel and it's not local.start but something else that consumes these 10 seconds? |

Good point, but not that easy unfortunately 
I disabled paraller booting and the same thing persists.
Does anyone know what/who is responsible for writing that text that comes between "Starting local ... Done" and Login prompt? It goes something like this "This is <hostname>.<domainname> <uname -a> <time>".
Two things happen after "Starting Local ... Done" they are that above mentioned "greeting" and login prompt. I think those are my prime suspects, unless someone else can point a finger at some process behind the curtains
EDIT: OK it seems to have fixed itself, I compiled cernel with CPU hotplugable support and HW/sensors for my mobo and now it boots properly, for the duration at least.
EDIT2: Second boot and the problem is back again, weird.

| Hm, then maybe it's just your ttys taking their time to spawn to the consoles. Reduce their number (/etc/inittab I think) and see if that makes a difference. |
