| 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. | |
