Decreasing the value of this parameter tends to reduce the speed
    with which working set limits are increased when the need arises.
    Normally, you should keep this parameter at a high value because
    a rapid increase in limit is often critical to performance.

    On Alpha and Integrity servers, WSINC specifies the number of
    pagelets by which the limit of a working set is automatically
    increased at each adjustment interval (which is quantum end). At
    a setting of 150, for example, the system increases the limit of
    a working set by 150 pagelets each time an increase is required.
    On Alpha and Integrity servers, the default value is 2400 512-
    byte pagelets (150 8192-byte Alpha and Integrity server pages).

    A value of 0 for WSINC disables the automatic adjustment of
    working set limits for all processes. Limits stay at their base
    values. You can disable the automatic adjustment of working
    set limits on a per-process basis by using the DCL command SET
    WORKING_SET.

    WSINC has the DYNAMIC and MAJOR attributes. On Alpha and
    Integrity servers, WSINC also has the AUTOGEN attribute.
