Howto reduce the time of startup?

mirojira · l33t Joined: 18 Feb 2006 Posts: 685

I have installed Gentoo and Archlinux at the same machine. The startup of Gentoo is about 40 sec. and startup of Archlinux is under 20 sec. I know that Archlinux is i686-optimised. So I think that I could optimise also Gentoo for my machine if I had known how to do it before I installed Gentoo.

I have ASUS P4P800-VM, Intel Pentium 4, 2.8 GHz, 1G RAM

What should I do to tweak my Gentoo installation?

See what's different in /usr/src/linux/.config between the 2 installations.

you could also watch to see which services gentoo loads vs archlinux, and check their docs to see what CFLAGS, and LDFLAGS they use when compiling. If you do find that out. Post it here, I would be interested to see how they compare to mine.

As a very rough observation, you can check the memory usage immediately after a reboot on both installations with "free -m".

This will at least tell you if more libraries are being copied to RAM when you boot Gentoo (which is usually proportional to the amount of services you have starting automatically, anything being preloaded, etc.).

arch linux is able to start services in parallel, by default gentoo isn't. you may want to give initng a shot (check the wiki, it is known to really speedup boot process - i haven't tried it myself though).

Gentoo can do semi-paralell startup; checkout /etc/conf.d/rc and make sure you have RC_PARALLEL_STARTUP="yes"

update to baselayout-0.12. I did and shaved 20seconds off my boot time!

Use init-ng (if you can make it work), or write your own init scripts on top of the SysV system. I've done the latter myself, and my Gentoo systems boot quite fast. Around 12-15 seconds from post to login on my 1.5 GHz laptop.

I solved problem ( wrong path to directory with .patch ) and finished the ebuild. Restarted and find out that network was not started and startx doesn' t work.
I manually set the conection, masked baselayout-1.12 and went back to the baselayout-1.11. Reboot and the same problem. I have fixed network connection
adding module e100 into /etc/module.autoload/kernel-2.6 which was overwritten. I am just looking for the reason why I can't run startx.
So I have lost courage to continue until I won't have the new instruction from you.

You probably want to take a look at /var/log/Xorg.0.log

I would follow the instruction on initng.org to use their overlay, and use the wiki to show you how to use it with lilo.

Here is a conversion for you:
