  Configurations
  ==============
  
  "perf"
  ------
  
  "all-timing"
      When set, additional statistic will be reported for each benchmark: best,
      worst, median average. If not set only the best timing is reported
      (default: off).
  
  "presleep"
    number of second to wait before any group of run (default: 1)
  
  "stub"
      When set, benchmark will only be run once, useful for testing (default:
      off)
