    Gunicorn performances are good enough for most cases. Most often performances can be improved in your application.

    +
    +

    Unicorn configguration

    +

    See Configuration for more informations.

    • worker_processes should be scaled to the number of processes your backend system(s) can support. DO NOT scale it to the number of external network clients your application expects to be serving. Gunicorn is NOT for serving slow clients, that is the job of nginx.

    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"
+
