High performance Python WSGI Web Server

Project description

What’s this

This is a fork of meinheld, the high performance python wsgi web server.

Minefield removes asynchronous feature from meinheld and have some experimental tuning.

And minefield is a WSGI compliant web server. (PEP333 and PEP3333 supported)


minefield requires Python 2.x >= 2.7 or Python 3.x >= 3.3.

minefield supports Linux, FreeBSD, Mac OS X.


Install from pypi:

$ pip install -U minefield

Install from source:

$ python install

minefield supports gunicorn.

To install gunicorn:

$ pip install -U gunicorn

Basic Usage

simple wsgi app:

from minefield import server

def hello_world(environ, start_response):
    status = '200 OK'
    res = b"Hello world!"
    response_headers = [('Content-type', 'text/plain'), ('Content-Length', str(len(res)))]
    start_response(status, response_headers)
    return [res]

server.listen(("", 8000))

with gunicorn. user worker class “egg:minefield#gunicorn_worker” or “minefield.gminefield.MinefieldWorker”:

$ gunicorn --workers=2 --worker-class="egg:minefield#gunicorn_worker" gunicorn_test:app


For parsing HTTP requests, meinheld uses Ryan Dahl’s http-parser library.


It is built around the high performance event library picoev.



Meinheld uses sendfile(2), over wgsi.file_wrapper.
