    Re: Speeding up the Boot time

    That is a pretty long boot time... what are your hardware specs? Also, do you have any programs automatically loading on startup?

    Theres also a util http://www.bootchart.org/ available to give you a heads up as to what is taking that long to load.

    That boot chart is unreadable, but I was able to pull of your specs, which are quite good.

    Regardless of what cpu or graphics you have, maybe BIOS settings need attention. Did you load any video drivers?

    Re: Speeding up the Boot time

    One immediate suggestion would be to purchase (if possible) more RAM. Though the minimum requirements for ubuntu say 512mb, things such as integrated graphics are going to eat up at least as much again, leaving your system low on memory regularly.

    4gb of DDR3 RAM will run you about 35 bucks on newegg, and more than pay for itself if the system you are using gets anything more than light use.

    Re: Speeding up the Boot time

    I never could read boot charts, but do look at log files. If some process in log file takes a long time, repeats and either then works or fails are then things to review.

    gksu gedit /var/dmesg

    My SSD shows 12.5 sec and this is a 7 year old dual core system. When booting from hard drive it is closer to 40 sec.

    type of entries to review:

    [ 3.715003] usbhid: USB HID core driver
    [ 5.612536] EXT4-fs (sdd3): mounted filesystem with ordered data mode. Opts: (null)
    [ 7.924725] Adding 3076412k swap on /dev/sdc11. Priority:-1 extents:1 across:3076412k
    I have found mounting partitions is slow, especially if they need chkdsk (NTFS) or fsck (ext4).

    Re: Speeding up the Boot time

    Theres a 5 second gap at the very start of your boot chart that says wait-for-root, which Im pretty sure is just the computer waiting for you to decide if you want to enter grub.

    Depending on how comfortable you are with editing your grub.cfg file, you can immediately shave that 5 seconds off by changing the GRUB_TIMEOUT= parameter. You can still access grub if need be, but for single-boot systems its pretty rare for the average user to need to access it at all IMO.


    On a related note, assuming this is a single boot (only one operating system) setup, did you leave part of the hard drive formatted as ntfs when you installed ubuntu? or reformat to ext3/4?

    Yes I know I have a dualboot system so I need to have that 5 second delay.......
