Defragmenter Performance issue

    Has anyone else noticed that when a Vista defrag is running, that your PC can
    entirely lock up for a period (on my PC it's about 3 minutes)?

    I believe that when the defrag program de-fragments the windows page file,
    or some other key system files, that the GUI basically stalls until the file
    is unlocked.

    The DWM continues to run and you can move windows around, but all processes
    become non-responsive. Basically all message queues are stalled.

    The drive rattles for ages and then the system comes back alive if you're
    patient.

    you can change the schedule for defrag running to a time when you are not likely to be using your computer.

    and NO it does not happen for me.

  4. I have recently been trying the Windows defragmenter and have scheduled it
    to run a 8pm every Tuesday. At this time i am actually still working on my
    machine and, i have to say, that i haven't noticed any performance
    deterioration or system locks. It has just got on with its job. I notice the
    hard drive light flashing during the defragment period, but other than that,
    and the fact that i had scheduled a defrag at that tine and day, i wouldn't
    have know defragmenter was running.

  5. Dfrgntfs does some fairly processor-intensive scanning when it starts up.
    At the command line defrag /a /v <vol> will perform this scan so you can see
    if the stalling is caused by analysis. That said, thus far I haven't had or
    seen this non-responsiveness here on any of my computers.

    Defrag should be doing low priority I/O even with the scanning. What is
    your cpu/ram? Is it consistent no matter how much or how little you are
    doing on the computer otherwise? None of this should matter but it might be
    interesting to recreate.

    Thanks

  6. Warder,
    email me and we'll take this offline to stop clogging up the group. My
    email is what you see in the newsgroup without the "online".

  7. You can still email me.
    There's a chance that it will repro anyway, since it looks like your system
    was possibly never horribly fragmented anyway :)

    Don't worry about that. There is so much sh_t on this group it is already
    pretty clogged up.

    You may want to try a real defrag program - like Raxco PerfectDisk. Tell
    them Roscoe sent you.

  10. Actually, Roscoe, I have to say that Raxco PerfectDisk is far superior for
    defragmenting the hard drive. I find it even better than Diskeeper.
