I ran 2 runs of daytrader 7 with and without patch on a 2 node power9
PowerNv box.
https://github.com/WASdev/sample.daytrader7
In each run, has 8 JVMs.

Throughputs (Higher are better)
Without patch 19216.8 18900.7 Average: 19058.75
With patch    18644.5 18480.9 Average: 18562.70

Difference being -2.6% regression
