Hi,

I just released performance 0.3, the Python benchmark suite, with 10 new benchmarks from the PyPy benchmark suite: https://github.com/python/performance

Version 0.3.0 changelog.

New benchmarks:

• Add crypto_pyaes: Benchmark a pure-Python implementation of the AES block-cipher in CTR mode using the pyaes module (version 1.6.0). Add pyaes dependency.
• Add sympy: Benchmark on SymPy. Add scipy dependency.
• Add scimark benchmark
• Add deltablue: DeltaBlue benchmark
• Add dulwich_log: Iterate on commits of the asyncio Git repository using the Dulwich module. Add dulwich (and mpmath) dependencies.
• Add pyflate: Pyflate benchmark, tar/bzip2 decompressor in pure Python
• Add sqlite_synth benchmark: Benchmark Python aggregate for SQLite
• Add genshi benchmark: Render template to XML or plain text using the Genshi module. Add Genshi dependency.
• Add sqlalchemy_declarative and sqlalchemy_imperative benchmarks: SQLAlchemy Declarative and Imperative benchmarks using SQLite. Add SQLAlchemy dependency.

Enhancements:

• compare command now fails if the performance versions are different
• nbody: add --reference and --iterations command line options.
• chaos: add --width, --height, --thickness, --filename and --rng-seed command line options
• django_template: add --table-size command line option
• json_dumps: add --cases command line option
• pidigits: add --digits command line option
• raytrace: add --width, --height and --filename command line options
• Port html5lib benchmark to Python 3
• Enable pickle_pure_python and unpickle_pure_python on Python 3 (code was already compatible with Python 3)
• Creating the virtual environment doesn't inherit environment variables (especially PYTHONPATH) by default anymore: --inherit-environ command line option must now be used explicitly.

Bugfixes:

• chaos benchmark now also reset the random module at each sample to get more reproductible benchmark results
• Logging benchmarks now truncate the in-memory stream before each benchmark run

Rename benchmarks:

• Rename benchmarks to get a consistent name between the command line and benchmark name in the JSON file.

• Rename pickle benchmarks:

  • slowpickle becomes pickle_pure_python
  • slowunpickle becomes unpickle_pure_python
  • fastpickle becomes pickle
  • fastunpickle becomes unpickle

• Rename ElementTree benchmarks: replace etree_ prefix with xml_etree_.

• Rename hexiom2 to hexiom_level25 and explicitly pass --level=25 parameter

• Rename json_load to json_loads

• Rename json_dump_v2 to json_dumps (and remove the deprecated json_dump benchmark)

• Rename normal_startup to python_startup, and startup_nosite to python_startup_no_site

• Rename threaded_count to threading_threaded_count, rename iterative_count to threading_iterative_count

• Rename logging benchmarks:

  • silent_logging to logging_silent
  • simple_logging to logging_simple
  • formatted_logging to logging_format

Minor changes:

• Update dependencies
• Remove broken --args command line option.
