If most of the programs scheduled in your IMS region are
OS/VS COBOL programs,
a performance benefit might be achieved by specifying lower values for the
Language Environment storage related
runtime options. For example, you could use the following storage values:
STACK(16K)
HEAP(4K,4K,ANY,4K,4K)
BELOWHEAP(4K)
ANYHEAP(4K)
