I will second Mr. Ross’ comments – we went directly from 15 to 17 (we abandoned the 16 upgrade) to take advantage of z/IIP exploitation – now at 19,
In our backend-only CVs, we are seeing 99% reduction in “billable” cpu – approx. 100 million transactions per week – from .00024 seconds/transaction to .0000031 seconds/transaction
Even if no internal performance enhancements, this is a MAJOR benefit of R17 + (your mileage may vary depending upon # of z/IIP processors available and how much they are already used)
