    I don't think i ever said 9s from POST. I did specify:
    NOTE: this was a cold boot, from the start of the bootloader to login.
    The time your BIOS takes depends on the configuration. I'm told that i can reduce that time by not auto-detecting things at POST.

    To illustrate where the 9seconds comes from, here's the actuall boot process of linuxICE:

    POST
    Bootloader
    Kernel loads into memory
    Init
    Login
    Graphical start
    nGhost, icepanel, etc

    POST takes about 10-12seconds,
    Bootloader takes maybe 1s
    Kernel -> Login takes 9s
    Graphical Start takes 2-3s
    nGhost and everything else < 1s.

    Total = ~27s

    After upgrading to 9.10, Kernel -> Login is about 3-5 seconds. Which would bring the total to 23 seconds.

    Shaving off 5-6s from the bios would put the total boot time at 17-18s, which is what most people get in windows using hibernate.

    The cool thing is, is LinuxICE is this fast without any tweaking like you'd have to do with windows to get it close to this fast. It loads to a full OS with all drivers loaded, wifi, networking etc.

    A 30 second video of a 25+ second boot which is supposedly a 9 second boot.

    shhh!

    The bootchart doesn't lie: the OS alone booted in 9s.

    Really, the more eyes I can get on LinuxICE at this point the better. I'm really excited about the progress it has made in the next release. It's becoming quite stable.

    LinuxICE addresses some major concerns that we in the forums try to solve fast booting/fast resume being one major one for a lot of people.

    Last update: after messing a bit in the BIOS, i timed the 9.10 based LinuxICE as 16.08s from POST. Not bad.

    Even from the boot loader (which is technically part of the os ) its not 9 seconds-but good to see your making progress.

    Alright heres the big question though since most forum members don't use full startup and full shutdown. How long for resume from s3 and resume from hibernate? Because I run win7 which gives me ~4second resume from hibernate and 1-2sec resume from s3.

    Hibernate in 9.10 (not using the tuxonice patches -which are faster), produced a total boot time of 18.82 seconds. That's about 2 seconds slower than cold boot :P. I'll try stock linuxICE when I get the chance which has the tuxonice patched kernel built in. I may see if I can patch this kernel. I tried last night to do a custom build, but something screwy happened and I lost my kernel config .

    I couldn't even time the s3 resume. It was too fast... probably <1s.

    I just installed a custom Atom specific kernel to my 9.10 LinuxICE2 system. I applied the tuxonice patches and removed a lot of unneeded drivers. The result is a much faster, 3mb kernel (as opposed to ubuntu's default 60+mb kernel). Tuxonice is *nice*. It uses LZO compression with results of 30%-50% to copy the contents of ram to the disk. Furthermore, it uses both cores on the atom330 to do the compression/decompression. The results are amazing over the default hibernate code. Much, *much* faster hibernates and resumes.

    Also, the tuxonice ppa now has kernels for 9.10.

    Adding the ubuntu-boot ppa to your apt sources should improve boot speed a little bit as well.
