> The class is not used and it rather harms to suggest to people that this
> would be the right way to do micro-benchmarks on the JVM. It even harms to
> suggest that micro-benchmarks are the right way to approach Java performance
> issues.
> Quote from http://code.google.com/p/caliper/wiki/JavaMicrobenchmarks
> "Why would I ever write a microbenchmark then?
> Most of the time, you shouldn't! Instead, slavishly follow a principle of
> simple, clear coding that avoids clever optimizations. This is the type of
> code that JITs of the present and future are most likely to know how to
> optimize themselves. And that's a job which truly should be theirs, not
> yours. "
> Tools to do microbenchmarks:
> http://code.google.com/p/caliper/ (from the team that also does Guava, the
> Google Java library, recommended by Joshua Bloch himself)
