Ubuntu 11.10 Down To 12-Second Boot
deadeyefred writes "Even though it's still only in alpha, it appears as though the forthcoming version of Ubuntu, version 11.10, will be much faster than earlier versions, according to this story. Quoting: 'After installing the OS onto a PC with an Intel Core 2 Duo E8400 at 3.00 GHz and a hard disk drive, we stop-watched boot-up time at 12 seconds — more than three seconds faster than the previous best time we’ve measured.' It looks as if the switch from GDM to LightDM will have a significant impact as Ubuntu gets closer to 'instant on' status."
I wonder what the boot time would be with SSDs?
How many people actually reboot their Linux systems?
Anybody who applies a kernel update, now that Oracle has acquired Ksplice.
I guess if you're on a laptop you might sometimes, but I just use Sleep functionality instead of cycles.
My Dell Mini 10 runs Ubuntu 11.04. Leaving it in sleep for a couple days will fully drain the battery. So if I know I'm not going to be near a charger for several hours, I shut it down.
but unity still sucks
If you're referring to upstart, IIRC that was actually an Ubuntu (Canonical) project.
Those extra three seconds during my monthly reboot are really going to add up!
That's what I was thinking. If the only advantage of switching from GDM to LightDM is that they can book 3 seconds faster, it's not worth it. Going from 15 seconds to 12 seconds is not significant at all.
In fact, here's a simpler rule. If you need to use your stopwatch to determine whether the boot sequence got faster or not, then it's not significant.

I typically don't run the media PC hooked up to my TV unless I'm actually watching a movie or listening to music. Because of a hardware peculiarity, the power button won't put it into standby like my desktop PC. So I just leave it shut off unless I'm using it. It's got 10.04 on it now and boot time is about 30 seconds (never timed it, I usually turn it on and head to he kitchen for a drink). I'd love a fast boot time.

Ash and Hickory, straight-grained and true, make excellent bludgeons, dandy for the cudgeling of vegetarians.
i get a 'restart your computer' message every other update.
Wealth is the gift that keeps on giving.
I shutdown my laptops a lot.
Hibernate takes forever to recover (I don't run only firefox...), so I don't use it.
Slep is Ok but for 2 or 3 times I forgot a laptop for several days and the battery got completely dead. Needless to say that its charge capacity is now around +-20%. Li-ion batteries should no be completely discharged.
Now I think twice before using sleep.
(I use Ubuntu)
Math is beautiful... e^(pi*i)+1=0
That's about how long it took me with Unity before I gave it the boot too!
They are a retarded thing to try and 'show-off'. Who cares that it takes you 12 seconds to start doing something, when the system you load into can't even get past screwing things up release after release. Ubuntu needs to fix it's many recurring, regressions, and add some functionality to other wise lacking programs/code.
I'm always skeptical of these "Boots in N seconds!" claims. Because often it takes another few -minutes- to log in, launch an application, and start doing something useful. We need a new metric. Say, the time it takes from power on to fully loading an uncached copy of example.com in a browser.
Hi, I've found that in most menuing systems (Windows XP primarily, although I use Ubuntu exclusively at home and it works similarly), if you left-click the "menu button" to open the menu, and then left-click and drag on the menu, you'll end up choosing a menu item much more often than if you left-click to open the menu, then move the mouse, then left-click again.
I've found that often (30%?) when I do the latter, I'll end up clicking outside of the menu, and possibly causing a side-effect. Whereas, if I left-click and drag on the menu, if I happen to release "off-menu" it won't count it as a click; the menu just disappears, and I merely need to start the gesture over. Which is much better than clicking something unexpected, which might delete things... This behavior has provided me with reduced swearing at the computer; YMMV.
I feel fantastic, and I'm still alive.
That depends if it's processor bound. I have a feeling the disk is pretty important, maybe more important.
With a bit of tweaking I managed to get debian squeeze to boot on my netbook in 20 seconds, on an atom processor. I think the SSD is probably the key there.
I wonder how much development time has been wasted saving you 12 seconds per month?
Development time that could have been used fixing Gnome3, PulseAudio, Systemd......
