    I am runing a P4T-E-1.7 GHz P4 512 RDRAM

    Aftern moving large files like copyiing one patition to another or moving a
    super large file my machine starts to slow down. I MEAN SLOW DOWN. You can see
    the taskbar come up slowly, Windows will open up slowly, yoo can actually see
    them writing to the screen. If you open a program after the transfer, it will
    take for ever. It is really awful. I have been dealing with this issue since I
    first got the P4T-E.

    I have done everything that can be done except change the mobo. I have
    installed the latest chipset drivers and the Intel Application Accelerator and

    Any ideas?

    With windows xp, I would disable drive indexing!

    Your trying to move more data than the OS likes..
    Basically If your trying to move 1 gig then you should have 3x + 500meg free
    so 3.5 gig free on BOTH drives for it to move over pretty good

    That's the only thing I can think of

    Sounds like your RAM is all tied up. This tiny program by Analogx will
    relase RAM that other programs should have but didn't. When you see a
    slow down double click the icon in the tray.

    Not true.

    You can move any sized file with practically any amount of memory - high or
    What you are describing is that if you have 'free' memory, Windows will
    leave the file data in memory as cached data since you have just read it so
    may be likely to want to read it again. Consequently you will see Windows
    memory usage in Task Manager (right click on the task bar to show it) swing
    around when copying large files. The moment this memory is required for
    anything else it is freed no a least used basis...

    I would check for Virii, indexing tasks as BoB indicates, virus scanner
    activity, non standard settings for windows priorities and cache settings.
    If you have ever downloaded any windows "optimisers" then they may be the
    culiprits as there are a lot of 'tweaks' that people are under the illusion
    will give enhanced performance when in fact Windows knows well how to manage
    things itself.

    What specific OS and version are you using? If you are using say W2K server
    (or NT or W2003) you can set memory priority to background tasks - this can
    cause this type of behaviour. (Under NT Workstation, W2K Pro, XP Pro, & XP
    Home priority is by default to foreground tasks). This will cause any cached
    data to be held onto more strongly and user applications to have memory
    aggressively trimmed. This setting is typical in a File Server situation
    where you are not supposed to do anything other than Manage the server when
    logged in on it - all priority is given to serving up files.

    If in doubt, and you are running XP, remove all 'optimisers', run virus
    scans, run spyware scans, and try a repair install of XP.

    Fire up Task Manager (right click on the task bar in W2K / XP) and watch
    what happens when you do a large file copy. Is there another task that gets
    busy? What does happen to memory allocation?

    Yea but windows will constantly swap the data, tit for tat over and over..
    If you are trying to move say 2 gig of data and you only have 200 meg free
    then It's going to do much more work and thus the movemnt slows down, this
    was my point

    I missed your original comment, but there is no reason why data transfers
    should be significantly different in speed whether you have 200Meg or 2Gig
    of RAM free.

    It's going to read the data and then write the data in chunks, probably much
    larger than the block size in order to increase speed, but there comes a
    point where there is no improvement... probably where your block-shift-size
    meets the standard read-ahead size, which is probably gonna be less than a
    Meg or two.

    OK I've just tried it - I copied a 700Meg file. Memory useage changed by
    like 200KB, which is probably the icons and file copy dialog box. What did
    increase was System cache... It went from ~460MB to 820MB and stayed high
    until high until I deleted the file. Now it was actually using System RAM
    for caching that file (I'm using a Server OS, so LargeSystemCache = 1), but
    can immediately dump that if an application requires that memory. Now,
    having the SystemCache increase massively is not used to increase the speed
    of Current File Transfers, only to increase the speed of accessing the files
    in that cache should I need to.

    Try moving something the size of your free space
    so if you have 6 gig left, move 6 gig worth of data
    hwo long does it take
    then move 2 gig worth of data
    how long does it take

    I bet it took more than 3* the length of time to move the 6 gig than it did
    the 2 gig

    Free space where? On the drive?
    I take it you mean on the drive then.
    Thats a whole different kettle of fish... data will unlikely be contiguous,
    so yeah, it'll take longer as there are more seeks. What does that have to
    do with the amount of free RAM you have?

    Why you talking about ram?
    Tim Changed "Drive Space" to "Memory"
    so I talked about "Swapping Files" trying to direct it back to Hard Drives

    Like I said earlier, I missed the first part of the thread, I thought we
    were talking about memory as RAM, rather then disk space.

    I didn't notice that (still can't, but hey).

    (from a previous post)
    Moving a 2Gig file when you have 200Meg (on the hard disk) free is either
    going to fail (if the source and target partitions are different) or take
    next to no time, since only the file reference is changed (this depends on
    your file system type). I'm not sure what you are talking about. Moving a
    file within the directory structure is unlikely going to involve touching
    the data in question (not on any file systems I know of, anyway).

    I thought he was moving from drive to drive
    he's moving partition to partition heh

    Little to no difference. The data must be physically moved in both cases.
    Obviously it'll be faster if drive to drive and on different channels.

    If all the other suggestions fail, I'd check the CPU temp and make sure
    its not throttling back and slowing itself down when it gets hot !?!

    Ive seen symptoms like this when the little jumpers on the drive dont match
    with its master/slave config -thats a lucky bet.

    You could try using a new cable,preferably a sheilded round one,or knocking
    the udma rate down a notch or two in the bios,or trying pio mode 2.

    I dont know it, but heard some say the intel app'acceler' can make things
