Boot time ?

[Maike05]

Hi, i'm considering to install Ubuntu on my futur Nc10, what is the boot time with it ? (power button pressed until icons appears).

Thanks

I have not timed it recently but it took something like 80sec to wireless connection established.
to be honest the booting time has been a bit disappointing. When I start the XP installation it seems to bot faster. Of course I have never used it under XP so the installation is rather fresh. we all know how windows mysteriously grows with usage. (my work laptop boots for some 5min
If I remember I will time my next boot and post it here.

Intrepid is not the fastest distro to boot up, due to various aspects.
Anyway, in 2 weeks the new ubuntu will be released, jaunty. I'm testing it on a second partition and its boot time is much improved, I think it is almost half the boot time of Intrepid.
At the moment my advice is to wait for jaunty (or to install the beta version, of course).
I think I will drop the support for Intrepid on my repository when jaunty will be officially out (it would be just a waste of my time )

Considering boot time, I would opt for sabayon (Gentoo based, if you are new to linux and generally not tech savvy, I would not recommend starting with it).

If you'd like to try, there are a few improvements to be made to the ubuntu boot time. The init system used by ubuntu is called upstart, which starts your services asynchronously. There are a lot of tutorials on this, just google it. Things that are generally worth looking at is profiling boot (just add "profile" to kernel line in grub, next boot will be REALLY slow. This basically rearranges stuff on your drive so that boot can be read without the drive having to seek a lot) and generating a boot chart, which can help you with finding out whats taking your boot so long

Thanks for your answers !

Anyway, you didn't answer my question, how much does it take to be on the desktop and to see the icons ?

Thanks

From when I press the power button to when I can click icons on desktop:

- Intrepid, 85 sec
- Jaunty, 50 sec

[kadrach]

~90 sec cold boot to gnome+firefox loaded.

But i rarely turn it off anyway, s3 sleep works just fine

I confirm the info.
Don't forget you can use a netbook derivated Intrepid ubuntu distro. You normally gain 25s compared to Intrepid and even more when they will update to Jaunty. So using Jaunty is a good first approach before trying anything else.

Hello,
Using Karmic with encrypted home, I boot (from power on to desktop) in 70s. It is slower than Jaunty (50s) on the same NC10 without home encrypted. What are your values with home either encrypted or not?

[FabriceV]

Boot time from hibernation is 40s (home encrypted).

[voria]

From when I press the power button to when the desktop is ready, with grub timeout set to 0 (instant boot), gdm autologin and not encrypted home, on battery powered:

Normal boot: 46 sec.
Boot from hibernation: 35 sec.

I did not believe that encrypted home impacts so much the boot time !? I have begun to remove unnecessary packages and processes, but that impacts mostly HDD and memory.
PS: Good point - there are less "abusive" dependencies, so it is easier to remove more packages.
