Project Purpose

This project was created to demonstrate and benchmark one form of Python-Rust FFI for the Colorado Springs Python user group called PySprings.

Benchmarking

I have included results from running the benchmark in the benchmark_results.md file in this repo.

Running the benchmark

There are two steps to running the benchmarks. The first is easy but will take a while, simply run the following commands:

$> virtualenv venv --python=python3
$> source venv/bin/activate
(venv) $> pip install -r benchmark.reqs.txt
(venv) $> python benchmark.py

After running those commands the results should be printed for you. However these results do not contain the run for pypy. In order to benchmark pypy some extra steps are required.

First, create a virtualenv with pypy as the interpreter:

$> virtualenv pypy-venv --python=$(which pypy3)
$> source pypy-venv/bin/activate

Now install the dependencies into this new environment. The installation of pillow may require you to have the libjpeg-dev headers installed.

(pypy-venv) $> pip install -r bencmarks.reqs.txt

Now run benchmark.py with the --python-only flag to get your pypy times.

(pypy-venv) $> python benchmark.py --pure-python
