MPW LOWAITLIMIT
MPW_LOWAITLIMIT is a system parameter that specifies the threshold at which processes in the miscellaneous wait state MPWBUSY are allowed to resume. MPW_LOWAITLIMIT increases system performance for fast processors with large memories by reducing the amount of time processes spend in the MPWBUSY wait state.
MPW_LOWAITLIMIT has the AUTOGEN and DYNAMIC attributes.
