      JMH: Specify the time unit to report the results
      JMH: State objects
      Jmh: @Setup, @TearDown fixture methods
      Jmh: be cautious with dead code
      JMH: Get the individual operations cost with @OperationsPerInvocation
      Jmh: @Param: Benchmark with different values
      Run JMH benchmarking from a junit test
      JMH: result format types
      Send the jmh log messages to a file
