Release early, release often: performance 0.1.2 has been released! The first version supporting Windows. I renamed the GitHub project from python/benchmarks to python/performance. All changes: * Windows is now supported * Add a new ``venv`` command to show, create, recrete or remove the virtual environment. * Fix pybench benchmark (update to perf 0.7.4 API) * performance now tries to install the ``psutil`` module on CPython for better system metrics in metadata and CPU pinning on Python 2. * The creation of the virtual environment now also tries ``virtualenv`` and ``venv`` Python modules, not only the virtualenv command. * The development version of performance now installs performance with "pip install -e <path_to_performance>" * The GitHub project was renamed from ``python/benchmarks`` to ``python/performance``.

Also, you may have several Python 3s installed (the system 3.4, a custom 3.4, a custom 3.5, a custom 3.6...) so a CLI script is much easier to use. Regards Antoine.

Rename python/benchmarks GitHub project to python/performance?
by Victor Stinner 26 Aug '16

Hi, For the first release of the "new" benchmark suite, I chose the name "performance", since "benchmark" and "benchmarks" names were already reserved on PyPI. It's the name of the Python module, but also of the command line tool: "pyperformance". Since there is an "old" benchmark suite (https://hg.python.org/benchmarks), PyPy has its benchmark suite, etc. I propose to rename the GitHub project to "performance" to avoid confusion. What do you think? Note: I'm not a big fan of the "performance" name, but I don't think it matters much. The name only needs to be unique and available on PyPI :-D By the way, I don't know if it's worth it to have a "pyperformance" command line tool. You can already use "python3 -m performance ..." syntax. But you have to recall the Python version used to install the module. "python2 -m performance ..." doesn't work if you only installed performance for Python 3! Victor

FYI it's now fixed: the development version of the benchmark suite now installs the performance module using "pip install -e <path>" in development mode, but "pip install performance==x.y.z" in release mode.

performance 0.1 (and 0.1.1) release
by Victor Stinner 24 Aug '16

24 Aug '16

Hi, I released a first version of the Python benchmark suite. (Quickly followed by a 0.1.1 bugfix ;-)) It is now possible to install it using pip: python3 -m pip install performance And run it using: pyperformance run --python=python2 --rigorous -b all -o py2.json pyperformance run --python=python3 --rigorous -b all -o py3.json pyperformance compare py2.json py3.json Note: the "python3 -m performance ..." syntax works too. It creates virtual environments in ./venv/ subdirectory. (I may add an option to choose where to create them.) performance 0.1.1 version works well on Linux with CPython. There are some know issues on Windows: https://github.com/python/benchmarks/issues/5 I don't consider the PyPy support as stable yet. I used the "performance" name on PyPI, because "benchmark" and "benchmarks" are already reserved. The Python module is also named "performance" and comes with "pyperformance" script. I made a suble bugfix: requirements.txt now uses fixed version rather than ">=min_version". For example, "perf>=0.7.4" became "perf==0.7.4". I expect to get more reproductible benchmark results with fixed versions. Before a release, we should not forget to update dependencies to test the most recent versions of Python modules and applications. Now the development version always install performance 0.1.1 (see performance/requirements.txt). I should fix this to install the development version of performance/ when it is run from the source code (when setup.py is available in the parent directory?). Victor

The benchmark was called "bzr_startup", bit I agree that "django" mus be renamed to "django_template". There is an HTTP benchmark, tornado_http, using the local link (server and client run in the same process if I recall correctly). Victor

Perhaps call the benchmark "bzr-startup" to emphasize the aim is to measure how long it takes bzr to start in general, moreso than how long it takes to print the help message?

Let's not have it called "bzr" though because it gives the wrong impression. The same way unladen swallow added a benchmark and called it "django" while not representing django very well. That said, likely not very many people use bzr, but still, would be good if it's called bzr-pyc or simpler - have a benchmark that imports a whole bunch of pyc from a big project (e.g. pypy :-) Cheers, fijal
