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.
