    Finally a topic about this.

    My dad got an MBA 11" 128GB/2GB on Thursday here in the Netherlands.
    And the first time and couple of times after it booted in 15 sec.

    But when he installed the update to iTunes is began booting in 25 to 35 sec.

    i Tried the usual suspects as repairing permissions and even disabling spotlight.
    But no go still booting in 35 sec.

    So what i did was a clean reinstall from de USB stick and although that saved me 1.2GB of space (left out the other languages) it never booted in 15 seconds.

    Hopefully my own ordered Air 13" 128GB/4GB will arrive this upcoming week, so i can see what mine does with these times.

    I personally hope that there is a setting or something that i'm missing to get it back at 15 sec. Although it looks like some strange thing apple did to it ;)

    You guys are looking for, and subsequently trying to fix, problems that de facto do not exist.

    You are absolutely right, and i don't really care if it boots in 15 or 30 seconds, because its still 30 seconds faster than my old MBP.

    Ant it will stay in sleep most of its time with its flash storage.

    But it was noticeable that it jumped from 15 to 30 seconds.

    I understand that boot times are not going to be spot-on even on two identical machines. However, isn't it a bit weird that 2 brand new machines have a time variance of a quarter of a minute? What causes this?

    Interesting even a fresh install would not take it back to 15 seconds.
    Just wondering why, one takes 2x as long...

    How about 15 secs with no network setup, and 30 sec with one ?

    Plugged in vs unplugged?

    Some power saving setting changed
    putting the CPU is speedstep mode vs running full speed all the time?

    Apple wanting a better out of box experience :) ?

    Reboot it 10 times in a row. Mac OS uses aggressive caching to speed up boot time. Things like system updates invalidate all caches and they need to be rebuilt. Each reboot trains the cache a bit more. After a few it should be back at full speed.

    Too bad there is no Soluto for Mac. That program took my old 4-year old and never reinstalled windows XP box from a 5 min boot down to 2.75 minutes (by disabling or delaying boot time cruft). When I upgraded to a box with an SSD and Windows 7, it took my boot time from 39 seconds down to 23 seconds and is always there to monitor system changes that lengthen boot, tell me what they are and what their individual impact is (as well as keep a complete history). After a program install, the next boot is slower because of smart caching issues in Windows 7, but the boot after that will be fast again.

    Soluto does that by disabling 3rd party services at boot-up mainly. Windows is far more infested with software that wants to start during boot than Mac OS. If you wanna see what 3rd party apps boot during startup on Mac OS simply look into /Library/LaunchDaemons, /Library/LaunchAgents and /Library/Extensions.

    The things that automatically start when you login you can check in System Preferences -> Accounts -> Login Items.

    That's about it.

    Not true at all. Picasa doesn't (didn't?) use that, nor do some Windows emulation programs, and other various processes that don't obey Apple's strict specifications. It was so bad that, once, I took my computer into an Apple store and was told that my hard drive was failing because of the long boot times.

    2 years later, the hard drive still works great without as much as a SMART error.

    There are ways to simply list startup processes in windows as well (many more places, of course), what Soluto tells you is how much time each of them takes so you can decide if the function it provides is worth having right at the start. Just having a list is useless unless you want to spend lots of time individual disabling them and rebooting to test. Soluto removed the need to ever do this. Its definitely a godsend for Windows.

    I just did a cold restart on my MBA 11.6 all stock and it only took almost 15 seconds. it was 14.8 for mine. I thought that was fast and pretty good. I am going to be testing my battery life later and see what happens with all of the stuff I normally do on my MB.

    My 13" averages between 17 and 19 seconds.

    I find that two second differential extremely stressful...

    Then there's a distinct lack of hard drive noise.

    Why Apple shipped it in perfect working condition is a mystery to me.

    Oops... Sorry, I forgot humor is off limits... :)

    I agree. A computer should be grinding and make "thinking" noises whenever you give a command.
    All this speed en silence is just crazy!

    Totally! I miss the honking noise my C64's drive made every time the computer did anything. THAT was a machine that let you know it was doing something!

    I tried booting up a air at the store, my first gen unibody alu macbook with intel ssd boots up faster

    Mine takes 21 seconds, I've had the same os install for almost a year, the 11 inch air took 26 seconds after multiple attempts, its not really suprising simce my intel x-25 M G2 is better

    In the benchmarks people have posted here the new MacBooks with 128 GB are faster than the Intel (according to Geekbench)

    And the start up time is supposed to be 15 seconds, not 26... Weird..

    I genuinely don't understand the 15 second boast at all.

    My white 3 year old crackbook w/ Intel 180gb SSD boots from power off -> firefox desktop in just over 15 seconds. That is hardly 'instant on'..

    False advertising in my opinion.
