zIIP Experiences

With the constant focus on controlling MIPS consumption, IT staffs are being pressed to get every cycle possible out of the zIIP specialty engines. There are two methodologies involved in maximizing off-load potential: 1) ensure everything that is currently eligible is getting access to zIIP cycles and tune appropriately 2) then look at other avenues to increase potential off-load. We will delve into both of these to investigate maximum zIIP exploitation and discuss the reality of current customer environments.
