Optimizing z/OS system and application performance today is all about having
data as close to the processor as possible when it's needed. Despite some
incredibly fast I/O times today, memory is still orders of magnitude faster and
(still) the only good I/O is no I/O. Keeping data in memory can not only improve
application performance but reduce CPU consumption as well. Fortunately, many
systems today have sufficient memory to make potentially significant
improvements. But memory is not infinite so how do you find the best
opportunities for improvement? In this session Scott Chapman will discuss data
sources and methods to find, evaluate, and implement I/O reduction
opportunities. You're sure to leave with good ideas that will help you eliminate
unnecessary I/O and improve application and system performance.
