I/O, I/O It’s Home to Memory We (Should) Go
Date/Time: 12/13/2023 10:00 a.m. – 11:00 a.m. CT
Scott Chapman, CIO & Director of Software Design and Development, Enterprise Performance Strategies, Inc.
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.
