    Ironically, Microsoft offers a choice here.

    In the registry (NT and W2K at least, don't know about XP:)

    HKLM\SYSTEM\CurrentControlSet\Session Manager\Memory Management
            LargeSystemCache : REG_DWORD
                    0: prefer application code over cached data
                    1: prefer cached data

    Also:

            DisablePagingExecutive : REG_DWORD
                    1: don't allow kernel code to be paged out

            IOPageLockLimit : REG_DWORD
                    controls the amount of memory that can be locked for I/O
