REMEMBER: The numbers below are just data. To gain reusable insights, you
need to follow up on
why the numbers are the way they are. Use profilers (see -prof, -lprof),
design factorial
experiments, perform baseline and negative tests that provide experimental
control, make sure
the benchmarking environment is safe on JVM/OS/HW level, ask for reviews
from the domain experts.
Do not assume the numbers tell you what you want them to tell.
