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

    On Alpha and Integrity servers, 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.
