Page File with Vista

  1. I just want to know how to turn down the page file usage. I tried going to performance ect. and setting the page file to 1gb and when i restart the same amount of paging is used. I.E. at the desktop my physical mem usage is around 756mb and paging is around 938. when I run Bioshock for example physical goes to 1.5gb and paging 1.8gb even though i set it to 1gb in the performance settings. Why isnt vista obeying me. FYI i have 3gb of ram. Thanx

    Just to confirm

    click the Start button
    click Control Panel
    click System and Maintenance
    click Performance Information and Tools
    click Advanced Tools (in the Tasks pane at the left side of the dialog box)
    click Adjust the appearance and performance of Windows.

    After answering the User Account Control prompt, you’ll arrive at the
    Performance Options dialog box. You’re nearly there

    click the Advanced tab, and then click Change.

    Memory is not used as most would assume. The typical assumption is
    real + pagefile = memory available​
    when in fact
    pagefile = memory available​

    If you take the pagefile to ZERO, then there is no virtual memory available and
    you've basically regressed the machine back into 8086 cpu processing

    A modern system uses VM (Virtual Memory) into which processes are mapped
    and the paging systems gives each process 'real memory' for execution.

    If you want the best performance
    • maximize REAL memory
    • run a large pagefile size (~2 or 3x real)
    • reduce the number of running programs to the absolute minimum
