In my JMH benchmark runs, I often find that ambient differences (from the jdk processes, the random test data generated, etc.) hide the actual performance difference caused by the patches. Hence, I need help in these two area: 1. I probably need to make a baseline benchmark that can discount the fundamental differences between jdk processes. What should it be? 2. How do I generate consistent data set for all test runs to avoid contributing to errors? ------------- PR: https://git.openjdk.java.net/jdk/pull/6532
