Increasing the value of this parameter tends to increase the
    speed with which working set limits are decreased when the need
    arises.

    On VAX systems, WSDEC specifies the number of pages by which
    the limit of a working set is automatically decreased at each
    adjustment interval (which is quantum end). At a setting of 35,
    for example, the system decreases the limit of a working set by
    35 pages each time a decrease is required.

    On Alpha and I64 systems, WSDEC specifies the number of pagelets
    by which the limit of a working set is automatically decreased at
    each adjustment interval (which is quantum end). At a setting of
    35, for example, the system decreases the limit of a working set
    by 35 pagelets each time a decrease is required.

    WSDEC has the AUTOGEN, DYNAMIC, and MAJOR attributes.
