   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.
