Hello<br />
We had our application running on IBM i series V5R4 machine.<br />
After the upgrade of OS to V6R1 on the same machine without any change in the application.<br />
application is giving performance issues like huge CPU consumption, output delay etc...<br />

IBM i series V6R1 performance issues

A mainframe operating system is networking software infrastructure that allows a mainframe computer to run programs, connect linked machines, and process complex numerical and data-driven tasks. Modern mainframe design is generally defined by redundant internal engineering, extensive input-output facilities, strict backward compatibility with older software, high hardware and computational utilization rates and high stability and reliability. Well-known operating systems include IBM z/OS, z/VM, zTPF, z/VSE, OS/390, and their predecessors, along with MCP for Unisys ClearPath, and NonStop OS/Guardian on HP/Tandem, and questions regarding the IBM midrange operating system called IBM i, OS/400, and i5/OS.

Mainframe OS

Operating systems perform basic tasks, such as recognizing input from the keyboard, sending output to the display screen, keeping track of files and directories on the disk, and controlling peripheral devices such as disk drives and printers. For large systems, the operating system makes sure that different programs and users running at the same time do not interfere with each other. The operating system is also responsible for security, ensuring that unauthorized users do not access the system. Operating systems provide a software platform on top of which other programs, called application programs, can run.
