Optimized ADRDSSU CPU usage for uncompressed Striped Datasets backup

WHEN CALLING ADRDSSU TO DUMP A non-compressed SEQUENTIAL DATASET TO TAPE THE AMOUNT OF CPU FOR PROCESSING A 16 STRIPE DATASET WITH OPT(4) IS APPROXIMATELY 500-700% OF THE CPU USED TO DUMP THE SAME DATA FROM A NON-STRIPED OR SINGLE STRIPED DATASET WITH OPT(4). IN FACT THE MORE STRIPES INVOLVED THE HIGHER THE CPU USAGE. DIFFERENT OPT PARMS CAUSE DIFFERENT RESULTS BUT THE OVERHEAD EXTREME IS MOST NOTICABLE AT OPT(4).
