Thanks for those numbers.
I'm guessing that zIIP time isn't in the Total CPU Time, so we are
comparing user+sys in the second with Total CPU in the first? So it
looks like Java overhead is about ~40% in this case? Not too
dissimilar to what I found, depending on whether Java did any
processing of the records.
