One of our customers had issues with Java workloads spilling over onto
GCPs due to the 2-1 constraint. It cost them serious money. Moving to a
z13 with faster zIIP processors solved the problem.

But you can use on PROJECTCPU in IEAOPTxx to simulate zIIPs and read
the RMF reports to see what is reported as zIIP-eligible work. And,
you can use the non-zIIP time in that same mode to estimate the
probable effect on your 4-hour rolling average CP busy.

specialty engines ?
