ACP_XQP_RES

   ACP_XQP_RES controls whether the XQP is currently in memory.
   The default value (1) specifies that the XQP is permanently in
   memory. Change the default only on restricted memory systems
   with a small number of users and little or no file activity that
   requires XQP intervention. Such activity includes file opens,
   closes, directory lookups, and window turns.
