In most cases, VPE functions without region size changes. However, a larger region enhances sequential access and may be required if LSR below the line is used. VPE writes messages, which indicate if a larger region would enhance buffering. If VPE does not ask for a larger region size, increasing the region does not improve performance.
Note: In order to avoid making changes to each job's region size, you can set IEALIMIT using an SMF exit.
LSR above the line can be used. The additional storage used below the line by VPE for code and tables is minimal.
