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.

NOTE: Current JVM experimentally supports Compiler Blackholes, and they are in 
use. Please exercise
extra caution when trusting the results, look into the generated code to check 
the benchmark still
works, and factor in a small probability of new VM bugs. Additionally, while 
comparisons between
different JVMs are already problematic, the performance difference caused by 
different Blackhole
modes can be very significant. Please make sure you use the consistent 
Blackhole mode for comparisons.
