IE8: Excessive memory allocation and usage?

    WinXP Pro SP3 all MS updates
    2GB RAM
    Dell Latitude D600 laptop, fyi.

    In reviewing the Task Manager processes it appears that IE8 allocates and
    uses an excessive amount of memory. For example, sorting the Processes by
    Mem Usage currently yields one iexplore.exe as using 651K and another one at
    157K. Still others at 67K, 57K and 26K. The smaller one's seem fine but the
    651K and 157K seem excessively high.
    1) Is this actually the result of IE8 or is it the websites (Yahoo etc.)?
    I've got 4 tabs and this "New Question" open for IE8.
    2) Is there a BETTER way to determine which tab is the 'offending' memory
    and CPU usage since ALL processes for iexplore.exe have the same Image Name.
    When I've terminated the process of iexplore.exe all the processes
    terminate. It appears that any open window related to IE8 has an associated
    iexplore.exe Image Name.
    3) I've also noticed that I'll have IE8 pegged at 100%. Any reason why or
    some perspective here?

    I have found that I normally need to take IE8 down during my normal work day
    and work functions. Currently, with the above IE8 information my Performance
    tab shows Physical Memory (K) with 2GB, Available 514K and System Cache of

    I also recently received a system warning on low resources which caused the
    Paging file to expand. [This may not be totally true as I'm recalling it
    from memory relative to my Windows message.] The Event Viewer for IE does
    not show any entries - which seems odd in some ways! I also didn't find any
    entry into any of the Event Viewer logs for the low-resources message.

    I'm not too sure I found what you were thinking about. The link covers quite
    a bit on IE8 beta and S7 beta testing.
    Can you be more specific at least relative to your link? Got any ideas
    without the link?

  4. Everything in the blog entry (including Loosely-Coupled IE & Automatic Crash
    Recovery) applies to IE8 Final.

    "Combined, LCIE and Automatic Crash Recovery provide a really innovative and
    graceful way to recovery from crashes."

    In Task Manager | Processes tab, you will see two (2) instances of
    IEXPLORE.EXE for every one (1) IE8 window open at the time. I suspect this
    may be the reason you consider the amount of memory being used at the time
    to be excessive, Tom.

    Thanks for the insight that for each tab I have two (2) IEXPLORE.EXE
    processes. I never would have figured that one out.
    Any idea on the 600K+ memory allocated for a tab? Seems very high to me.
    Is this a Yahoo 'feature' or someone else's?

  6. YW.

    Try this:

    1. Reset your IE home page to BLANK then close all IE windows.

    2. Open one (1) IE window to the new (about:blank) home page: Does TaskMan
    show two (2) instances of IEXPLORE.EXE? What's the memory level for each?

    3. Now, tell me what your original home page had been.

    Try running IE in No-Addons mode, and check the memory usage. With IE7Pro
    running on my home PC IE8 often runs around 150MB per process (a lot of that
    appears to be due to Easy Home Page, but I find it really useful), yet in
    No-Addons mode they use around 20KB each. While IE will adjust it's memory
    usage to accomodate the page being rendered, if you find that it's using a
    lot as soon as you start it then it'll be due to add-ons being loaded.
    However, the figures you've given are all under 1Mb which to me seems small
    if that's a complex page being rendered.

    I think what Tom meant in his first post was that he was having iexplore
    processes with 651K (~638MB), 157K (~152MB) and other little ones with 67K
    (~64MB), 57K (~55MB) and 26K (~25MB) of RAM usage. If you add them up, the
    number produced looks painful on a system with only 2GB RAM.

    651K is not 638MB - it's 0.638MB! Same goes for your other figures, you're
    off by a long shot. When you add those up IE is using a small fraction of
    the total system memory. Where did you get the idea that Tom meant MB
    instead of K? Or do you think that the K in Task Manager is actually M? If
    so, why have I currently got, for instance, explorer.exe using 108,704k,
    which by your terms would be 106GB, on system with only 1GB of RAM?
