    Re: Speeding up the Boot time

    Gotcha... perhaps someone better than I can see anything out of sorts, but aside from the 5 sec delay, and cups loading at the very end, it looks like its booting in 45-50 seconds, which isnt bad on a hdd system.

    Definitely though if youre using Win on that system as well, you might want to looking at adding more ram... its the best bang for your buck that youre going to get for performance (and Im honestly surprised youre not plagued by windows low memory messages already).

    Re: Speeding up the Boot time

    I'm using a HP Probook 4530s (slightly higher specs than yours, 7200 RPM HDD, 3GiB RAM) and have a boot time of about 20 seconds. Seems to me something else is going on than a lack of RAM.

    I'm not used to reading bootcharts, but is it correct your computer spends 8.5 seconds running fsck? I don't think that should happen every time you boot.

    I think, as oldfred alluded to, check the var logs. Specifically, syslog, kern.log. Look for any errors and/or failed messages.

    Follow the below links for my syslog and kernlog.

    And the size of the kernlog is 16MB.Is this normal???

    Yes I think Mounting NTFS partitions is taking more time in boot........

    gksu gedit /var/dmesg
    gksu gedit /var/dmesg This code returns nothing means my dmesg is empty....

    Post this:
    gksu gedit /var/log/dmesg

    do you have anything plugged in that you do not need to?
    Have you settings in BIOS for devices you do not have? One user had no floppy drive yet BIOS was reporting it, and system had a heck of time looking for something that does not exist.
    Another had a DVD in DVD drive and sytem tried running fsck on it??

    Any services you do not use, like bluetooth, wireless, Ethernet on IPv6 or anything else?
    I rarely use wireless on my laptop so I turn it off.

    Re: Speeding up the Boot time

    Your kern.log is just to big to look at for me, but syslog is filled with "Asking for cache data failed". There is a bug report on that. Read this answer on the data failed question.

    Also in the syslog is "Test WP failed, assume Write Enabled". More answers here.

    Re: Speeding up the Boot time

    This says you are booting in 27 sec? Now with my system BIOS takes 10 sec, grub about 5, and system 25. If from hard drive BIOS & grub are same but system takes 40+ sec.

    Longer entries:
    [ 5.676497] sd 4:0:0:0: [sdb] Attached SCSI removable disk
    [ 9.397885] EXT4-fs (sda6): mounted filesystem with ordered data mode. Opts: (null)
    [ 21.628294] Adding 4193276k swap on /dev/sda8. Priority:-1 extents:1 across:4193276k


    Last entry
    [ 27.805872] iwlwifi 0000:43:00.0: Radio type=0x1-0x3-0x1

    It looks like the mount of an external drive takes some time? It is the time between posts that is how long, but I do not know if post is after it completes previous or at beginning of task?

    Re: Speeding up the Boot time

    IF 27 sec is boot time with a hard drive, I am not sure you have any problem.
