By | October 30th, 2012|App Performance|

Today's modern applications are not restricted to a single platform. Yet, in many ways, mainframe management and administration professionals are still tackling performance issues and problem resolution using the same methods they did when mainframe applications were all COBOL and never strayed off of the centralized mainframe computing platform. And [...]

Mainframe application and subsystem CPU consumption drives MIPS usage and MIPS usage drives mainframe hardware and software costs. If your mainframe performance is poor, that increases CPU usage – and poor performance costs money. These performance dogs and resource hogs are often overlooked areas of waste that, when identified and corrected, can put dollars back in your budget.
