    Closing tab causes lots of hard drive activity

    I typically use a large number of open windows for applications and open tabs in IE. I also use standby a great deal. When closing IE tabs after standby had been used, there is always a great deal of hard drive activity that slows down the closing tabs I no longer want to use. Why is that? Can it be avoided?

    That would help: Win 7 and IE 11.

    Lots of apps + open tabs + Standby used often, sounds like you need more RAM (and/or a faster drive/SSD) to reduce paging data out to the swapfile on the hard disk.

    How much memory do you have and how much have you used? (Open Task Manager by right clicking on the taskbar.)

    cheers, Paul

    I have 8 GB of RAM.

    Right now I have 12 tabs open in IE and 16 windows open. Six are for a spreadsheet, one for Quicken, a couple pdfs, and Word, and I am using 4.7 GB of memory. I have seen it as high as 6+ GB, though.

    It doesn't happen every time. For example, right now I just came out of standby, browsed some websites, and closed some tabs, and the tabs closed virtually instantaneously without any hard drive activity. Yet other times it takes eight or nine seconds, approx., plus a lot of hard drive churning, to close a tab.

    I am already looking at adding RAM, doubling it to 16 GB, but it does not seem to be the source of the issue. Even if the page file was involved, why does there have to be hdd activity to close a tab?

    I have the same situation here. The more programs open within Windows OS, the more tabs open within the three browsers, when it's time to close some or all -- HD activity occurs. The answer - I don't know an answer.

    It depends on the content of the tab (paged or not); MS spreadsheets, Word, even Notepad are programmed to back up the data to page file because it's expected that the data will change. With a slow machine, or a fast one in a long, hard session, you can feel the stall/lag on opening a spreadsheet etc., you can't use the data until it's been backed up - once paged out, it then it loads and you can work with it.

    Check the Commit (GB) figures in TaskMan for clues on how much Total Memory is in use, eg. 2/11 is between 2 and 3 GB used out of a total of 11-12. If the Commit figure is 3GB higher than the amount of RAM in use (6GB RAM, 9GB Commit), then you have around 3GB paged out as well.

    Batch file WMI method of checking the actual page file amount in use, #34 here.

    The easiest way to work around/minimise the effect of it, is to reboot relatively frequently and have a large, fixed size, page file.

    Is IE set to Delete browsing history on exit? (At Internet Options, General tab.)

    Don't remember if IE11 on WIn7 supports "page look ahead". Check you IE settings - IE options | Advanced. Make sure "Enable flip ahead with page prediction" is disabled (unchecked).

    I also experience this. System is IE 11 on Windows 7. The effect is less when simply closing a tab and more when closing all tabs.

    But yeah, I can get 30 seconds or more of high levels of disk activity when doing this.

    IE: not set to delete browsing history; apparently doesn't support "Enable flip ahead with page prediction." With 11 windows open and 11 tabs open in IE: Memory used: 3.12 GB, commit is 3/15.

    Here is the output of the batch file. As best as I can interpret it, there is not much page file being used; I will have to run it again when I really have the system loaded:

    1 Instances of Win32_PageFileUsage

    Node AllocatedBaseSize CurrentUsage Description InstallDate Name PeakUsage Status TempPageFile

    BILLYBOB-HP6000 8063. 19. C:\pagefile.sys. 20141116171234.236015-300. C:\pagefile.sys. 19. . FALSE.

    I see that I am not the only one experiencing this. Might be a quirk of Windows and nothing can be done about it.

    What's also strange about this, ever since I first posted on the issue, I have gone into and come out of standby several times, and yet I haven't experienced the problem at all.

    I think I'll call it a day on this. Thanks for all the help.
