On a number of machines in the past, across different versions of Windows (2000, XP, and no Vista), I've enabled DisablePagingExecutive to try and improve performance. In each case, and I've had plenty of memory, and in the especially so in the current case. However, after enabling this registry tweak and rebooting, I've checked task manager after a while, and I still show a huge chunk of the kernel paged to disk, even though I have 2GB of physical memory free.
Has anybody ever used this tweak successfully? Ever? Maybe I'm viewing the wrong indicator when I check the task manager (Performance tab -> "Kernel Memory" section), but I'd like to prevent Windows from paging everything it can to disk, especially considering the amount of memory provided in desktops these days. It seems like a "Don't page to disk unless there's extreme memory pressure" option ought to exist - is there one?
