Faster than Flask

This is the code to accompany an article <https://medium.com/@pgjones/6x-faster-than-flask-8e89bfbe8e4f>_.

Running

Assuming you have at least Python 3.6, firstly to setup:

.. code-block::

$ python -m venv venv
$ source venv/bin/activate
$ pip install -r app/requirements.txt
$ cd app && gunicorn --config gunicorn.py 'run:create_app()'

Performance measurement

The commands used to measure the performance of the apps are,

.. code-block::

$ wrk --connections 20 --duration 5m http://localhost:5000/films/ $ wrk --connections 20 --duration 5m http://localhost:5000/films/995/ $ wrk --connections 20 --duration 5m --script post.lua http://localhost:5000/reviews/

Database

All of the above assumes you have the Postgres sample database <http://www.postgresqltutorial.com/postgresql-sample-database/>_ running locally with the following addition made,

.. code-block:: sql

CREATE TABLE review ( film_id INTEGER REFERENCES film(film_id), rating INTEGER );

and a dvdrental user/role to access the database.
