Hi, I released perf 0.9.6 with many changes. First, "Mean +- std dev" is now displayed, instead of "Median +- std dev", as a result of the previous thread on this list. The median is still accessible via the stats command. By the way, the "stats" command now displays "Median +- MAD" instead of "Median +- std dev".
I broke the API to fix an old mistake. I used the term "sample" for a single value, whereas a "sample" in statistics is a set of values (one or more), and so the term is misused. I replace "sample" with "value" and "samples" with "values" everywhere in perf. http://perf.readthedocs.io/en/latest/changelog.html#version-0-9-6-2017-03-15 Version 0.9.6 (2017-03-15) -------------------------- Major change: * Display ``Mean +- std dev`` instead of ``Median +- std dev`` Enhancements: * Add a new ``Runner.bench_command()`` method to measure the execution time of a command. * Add ``mean()``, ``median_abs_dev()`` and ``stdev()`` methods to ``Benchmark`` * ``check`` command: test also minimum and maximum compared to the mean Major API change, rename "sample" to "value": * Rename attributes and methods: - ``Benchmark.bench_sample_func()`` => ``Benchmark.bench_time_func()``. - ``Run.samples`` => ``Run.values`` - ``Benchmark.get_samples()`` => ``Benchmark.get_values()`` - ``get_nsample()`` => ``get_nvalue()`` - ``Benchmark.format_sample()`` => ``Benchmark.format_value()`` - ``Benchmark.format_samples()`` => ``Benchmark.format_values()`` * Rename Runner command line options: - ``--samples`` => ``--values`` - ``--debug-single-sample`` => ``--debug-single-value`` Changes: * ``convert``: Remove ``--remove-outliers`` option * ``check`` command now tests stdev/mean, instead of testing stdev/median * setup.py: statistics dependency is now installed using ``extras_require`` to support setuptools 18 and newer * Add setup.cfg to enable universal builds: same wheel package for Python 2 and Python 3 * Add ``perf.VERSION`` constant: tuple of int * JSON version 6: write metadata common to all benchmarks (common to all runs of all benchmarks) at the root; rename 'samples' to 'values' in runs.
