Description: About
        -----
        
        gunicorn 'Green Unicorn' is a WSGI HTTP Server for UNIX handle fast clients
        **and** sleepy application.
        
        This is a port of Unicorn (http://unicorn.bogomips.org/) in Python. Meet us
        on `#gunicorn irc channel <http://webchat.freenode.net/?channels=gunicorn>`_
        on `Freenode`_.
        
        Installation
        ------------
        
        Gunicorn requires **Python 2.5 or newer** (Python 3.x will be supported soon).
        
        Install from sources::
        
        $ python setup.py install
        
        Or from Pypi::
        
        $ easy_install -U gunicorn
        
        If you want to handle `sleepy applications <http://gunicorn.org/faq.html>`_
        you will need to install Eventlet_ or Gevent_.
        
        To install eventlet::
        
        $ easy_install -U eventlet
        
        Replace `eventlet` by **gevent** if you want to use `gevent`. You can now
        launch gunicorn with Eventlet or Gevent arbiter, see `Gunicorn usage
        <http://gunicorn.org/usage.html>`_ for more information.
        
        If you encounter errors when compiling the extensions for `gevent` or
        `eventlet` you probably need to install a newer version of libev_.

        Usage
        -----

        --log-file=LOGFILE    Log to a file. - equals stdout. [-]
        -d, --debug           Debug mode. only 1 worker.
        --spew                Install a trace hook
        --version             show program's version number and exit
        -h, --help            show this help message and exit
        
        
        Example with test app::
        
        $ cd examples
        $ gunicorn --workers=2 test:app
        
        Django projects
        +++++++++++++++
        
        For django projects use the `gunicorn_django` command::
        
        $ cd yourdjangoproject
        $ gunicorn_django --workers=2
        
        or use `run_gunicorn` command.
        
        add `gunicorn` to INSTALLED_APPS in the settings file::
        
        INSTALLED_APPS = (
        ...
        "gunicorn",
        )
        
        Then run::
        
        python manage.py run_gunicorn
        
        Paste-compatible projects
        +++++++++++++++++++++++++
        
        For paste-compatible projects (like Pylons, TurboGears 2, ...) use the `gunicorn_paste` command::
        
        $ cd your pasteproject
        $ gunicorn_paste --workers=2 development.ini
        
        or usual paster command::
        
        $ cd your pasteproject
        $ paster serve development.ini workers=2
        
        In last case don't forget to add a server section for gunicorn. Here is an example that use
        gunicorn as main server::
        
        [server:main]
        use = egg:gunicorn#main
        host = 127.0.0.1
        port = 5000
        
        Kernel Parameters
        -----------------
        
        There are various kernel parameters that you might want to tune in order to deal with a large number of simultaneous connections. Generally these should only affect sites with a large number of concurrent requests and apply to any sort of network server you may be running. They're listed here for ease of reference.
        
        The commands listed are tested under Mac OS X 10.6. Your flavor of Unix may use slightly different flags. Always reference the appropriate man pages if uncertain.
        
        Increasing the File Descriptor Limit
        ++++++++++++++++++++++++++++++++++++
        
        One of the first settings that usually needs to be bumped is the maximum number of open file descriptors for a given process. For the confused out there, remember that Unices treat sockets as files.
        
        ::
        
        $ sudo ulimit -n 1024
        
        Increasing the Listen Queue Size
        ++++++++++++++++++++++++++++++++
        
        Listening sockets have an associated queue of incoming connections that are waiting to be accepted. If you happen to have a stampede of clients that fill up this queue new connections will eventually start getting dropped.
        
        ::
        
        $ sudo sysctl -w kern.ipc.somaxconn="1024"
        
        Widening the Ephemeral Port Range
        +++++++++++++++++++++++++++++++++
        
        After a socket is closed it eventually enters the TIME_WAIT state. This can become an issue after a prolonged burst of client activity. Eventually the ephemeral port range is used up which can cause new connections to stall while they wait for a valid port.
        
        This setting is generally only required on machines that are being used to test a network server.
        
        ::
        
        $ sudo sysctl -w net.inet.ip.portrange.first="8048"
