WSINC

   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.
