Subject: Syncsort TPF 2.1 with zPSaver problems
We upgraded Syncsort to 2.1 late last year and have applied TPF 2.1 (what
Syncsort calls a bundle of PTFs at a maintenance level). That comes with
zPSaver
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
What is the general opinion out there on what portion of CPU cycles should be
spent in supervisor state?
Is more than 50% a bad thing?
Could having a logical processor to physical processor ratio of greater than 2
(e.g. 8 logicals in a 3 CP cec) be bad?

Has anyone heard any good rumors about what will be coming out next year as the
latest and greatest model?
z296?
Ec14?
