There is 1.5Gb RAM at the test computer, and usually, 900Mb of them are free. When I launch an application which takes about 500Mb, Windows 7 goes with swapping, and occasionally this leads to huge delays.. What I want is to exclude that app. from swapping due to high memory's usage.
Although the page file default policy is to write most unused pages to disk, the idea of what I see is writing everything at disk right at the moment when I launch that app and I'd rather prefer to see 1-2 apps crashing with[ ]out of memory.
However, disabling swap completely leads to annoying Firefox crashes at the normal work time, and that's the only reason for having page file at that machine.
