Embodiments include method, systems and computer program products for z Integrated Information Processors (zIIP) processing performance analysis and process management. In some embodiments, at least a portion of an application may be executed using a general-purpose processor of a mainframe computing device, wherein the at least the portion of the application comprises a zIIP-enabled process. A first set of data associated with the general-purpose processor may be collected. At least a portion of the application may be executed using a zIIP of the mainframe computing device. A second set of data associated with the zIIP may be collected. An efficiency percentage may be calculated using the first set of data and the second set of data. A portion of the application may be authorized to execute on the zIIP based on the efficiency percentage.
