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. -----Original Message----- From: IBM Mainframe Discussion List [mailto:IBM-MAIN@LISTSERV.UA.EDU] On Behalf Of Blaicher, Christopher Y.

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.

Some SRB routines today are much more robust and can do significant work, but that is what the z/IIP engines are for. 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.
