We just enabled zPSaver Suite on an LPAR on a z12 z/os 2.1 as a POC. We're
getting 72.1 percent offloaded to zIIP on that LPAR. There's a little savings
in IEBGENER, too, but too little to matter.
What I can't figure out is where the CPU time went, because I did NOT see the
72.1 percent show up in the zIIP column. I know the specialty engines are not
hamstrung like the 2827-H43-407 general purpose engines, but it looks the 1
zIIP on the CEC is 4 times faster! Can that be true? Any form of reality check
would be welcome here.

Go to http://www.syncsort.com/en/Products/Mainframe/ZPSaverSuite and see what
we can do on z/IIP engines. In a nutshell, we can offload about 90% of our
normal TCB workload to a z/IIP engine, your mileage may vary depending on a
number of things, but we can do an awful lot. This has been a multi-year
project by a number of very talented people.

What is the work done on a Ziip engine? As I understand other postings
(possibly incorrectly) the work runs under an enclave SRB.
Java and XML parsing to my mind are application code. I can't speak as to what
type of code DF/Sort and Syncsort are running on Ziip and Zaap.
