PFRATL

PFRATL is a system parameter that specifies the page fault rate below which the limit of a working set is automatically decreased. The unit of measure is the number of faults per 10 seconds of processor time. At a setting of 1, for example, the system automatically decreases the limit of a working set if it is faulting less than 1 page every 10 seconds. Increasing the value of this parameter tends to decrease the limits of the working sets, while decreasing its value tends to increase their limits. PFRATL has the AUTOGEN, DYNAMIC, and MAJOR attributes.
