  perf extension - helper extension to measure performance

  Configurations

  ==============

  "perf"

  ------

  "all-timing"

      When set, additional statistics 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 runs (default: 1)

  "pre-run"

    number of run to perform before starting measurement.

  "profile-benchmark"

    Enable profiling for the benchmarked section. (The first iteration is

    benchmarked)

  "run-limits"

    Control the number of runs each benchmark will perform. The option value

    should be a list of '<time>-<numberofrun>' pairs. After each run the

    conditions are considered in order with the following logic:

        If benchmark has been running for <time> seconds, and we have performed

        <numberofrun> iterations, stop the benchmark,

    The default value is: '3.0-100, 10.0-3'

  "stub"

      When set, benchmarks will only be run once, useful for testing (default:

      off)

----------------

Simple single entry
