Special performance considerations

XTP7NOTY flags are located in the APSGEXTP parameter area. See XTP7 parameter area (DSECT) for more information. XTP7NOTY flags should not be turned on unless a specific function is intended.
Retaining an often-used overlay or page segment over data set boundaries can improve printer throughput by eliminating the need to load the resource for each data set. Do not, however, retain resources arbitrarily. Page segments can take up substantial amounts of storage, and retaining overlays can force PSF to retain unneeded resources.
