What is mainframe performance tuning?

Mainframe performance tuning refers to the process of optimizing the efficiency and speed of mainframe computer systems. This involves analyzing system resources, workloads, and configurations to identify bottlenecks and make adjustments that improve throughput and response times. Techniques can include tuning parameters in operating systems, databases, middleware, and networking components. The goal is to ensure the mainframe operates at peak efficiency to support business applications and minimize downtime.
