Db2 for z/OS continues to advance through Db2 13 continuous delivery, introducing performance‑focused enhancements that impact SQL execution, system scalability, resource efficiency, and operational behavior. Effectively exploiting these capabilities requires understanding not only what has changed, but how the changes interact with workloads, subsystem configuration, and the underlying IBM Z platform. This session provides a technical deep dive into recent Db2 for z/OS performance enhancements, including features delivered through Db2 13 continuous delivery and insights gained from real customer experiences. We will examine how these updates influence critical performance areas such as CPU consumption, concurrency behavior, and subsystem scalability. In addition, we will cover monitoring and instrumentation updates, discussing how to interpret new or enhanced metrics and how they can be used to validate performance behavior and guide tuning decisions. Attendees will leave with concret
