    Doesn't this destroy existing "free" pages that have data in them that might be re-used later?  If it's based on what people run, wouldn't that data already be loaded from the last exit?  This may be good for initial start-up, when the memory is free, but then drive usage is pretty high during that time frame anyway.

    I'd be interested to know if this actually speeds anything up.

     
    • Yes, that's basically what it does.  I came up with some negative conclusions like yours after I finished experimenting with it.  You can read my findings here:
