Vista hibernate sometimes takes about 10 minutes

Discussion in 'Windows Vista Performance' started by D. Hendriks (Dennis), Nov 8, 2009.

  1. Usually, hibernation (which is set as my default shutdown option in the Start
    Menu), takes less than a minute. Sometimes however, it takes very long. It
    can get up to, or even more than, 10 minutes!

    I accessed the Event Viewer -> Applications and Services logs -> Microsoft
    -> Windows -> Diagnostics-Performance -> Operational, and filtered for Event
    ID 300. There are several 'Error' and 'Critical' Level events, where the
    'Critical' ones account for all of the problematic hibernations.

    Typical entry ('Error' level):

    Windows has resumed from standby:
    Standby Duration : 49564ms
    Standby Incident Time (UTC) : 8-11-2009 15:07:20
    Resume Duration : 21076ms
    Resume Incident Time (UTC) : 8-11-2009 20:30:12
    IsDegradation : false

    Problematic entry ('Critical' level):

    Windows has resumed from standby:
    Standby Duration : 506217ms
    Standby Incident Time (UTC) : 8-11-2009 0:40:23
    Resume Duration : 24673ms
    Resume Incident Time (UTC) : 8-11-2009 10:18:22
    IsDegradation : false

    On the 'details' tab, for the second on (the 506 seconds), I see:

    StandbySuspendTotal 506217
    StandbySuspendHibernateWrite 487203
    StandbyResumeHibernateRead 24150

    So, I'm thinking that it takes 487 seconds to write the memory contents to
    hiberfil.sys. I checked, and the fiile is not fragmented at all. Does anyone
    have an idea as to why it takes so long to write the memory contents to file?
    And why does it take long sometimes, while it usually goes much faster? Any
    help would be greatly appreciated.

    Some system details:
    - Windows Vista Business 64-bit English SP2 with all the latest updates.
    4GB internal memory.
    - QuadCore Intel Core 2 Quad Q9550, 2833 MHz (8.5 x 333)
    - Asus P5Q Deluxe (2 PCI, 2 PCI-E x1, 3 PCI-E x16, 4 DDR2 DIMM, Audio,
    Dual Gigabit LAN, IEEE-1394)
    - 4096 MB (DDR2-800 DDR2 SDRAM), 2x2GB
    - NVIDIA GeForce GTX 275 (896 MB)
    - ST3500320AS ATA Device (500 GB, 7200 RPM, SATA-II)

    Just a thought, but have you tried turning off hibernation, and if necessary,
    deleting the hibernation file, then turning hibernation back on, to see if
    that gets you back to the short hibernation times?
