If you were reading from one QSAM DASD DCB and writing to another QSAM DASD DCB -- let's say 20,000 133-byte records blocked half track -- would you expect to see a noticeable performance improvement (elapsed time and/or CPU time) from specifying a BUFNO greater than 5? What number might you specify to optimize elapsed and/or CPU time without "being ridiculous"? Any related considerations? Thanks,
