WSMAX sets the maximum number of pages on a systemwide basis for
    any working set. WSMAX is calculated as a quarter of the first
    32 MB plus a sixteenth of the memory from 32 to 256 MB, plus a
    sixty-fourth of the memory (if any) above 256 MB.

    This is intended to assist managers of systems that host large
    numbers of users whose working sets are not large. Systems whose
    user bases consist of a small number of users (or processes)
    that require large amounts of physical memory (for example,
    simulations) might need to set MIN_WSMAX to a value that
    satisfies the requirements of those processes.

    WSMAX has the AUTOGEN, GEN, and MAJOR attributes.
