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 -- Thanks and Regards Srikar Dronamraju
