+#       served. Exceeding this number results in the client
+#       getting an error when attempting to connect. It should

+# Worker processes

+#   workers - The number of worker processes that this server
+#       should keep alive for handling requests.
+#
+#       A positive integer generally in the 2-4 x $(NUM_CORES)
+#       range. You'll want to vary this a bit to find the best
+#       for your particular application's work load.
+#
+#   worker_class - The type of workers to use. The default
+#       sync class should handle most 'normal' types of work
+#       loads. You'll want to read
+#       http://docs.gunicorn.org/en/latest/design.html#choosing-a-worker-type
+#       for information on when you might want to choose one
+#       of the other worker classes.
+#
+#       A string referring to a Python path to a subclass of
+#       gunicorn.workers.base.Worker. The default provided values

+#
+#   worker_connections - For the eventlet and gevent worker classes
+#       this limits the maximum number of simultaneous clients that
+#       a single process can handle.
+#
+#       A positive integer generally set to around 1000.
+#
+#   timeout - If a worker does not notify the master process in this
+#       number of seconds it is killed and a new worker is spawned
+#       to replace it.
+#
+#       Generally set to thirty seconds. Only set this noticeably
+#       higher if you're sure of the repercussions for sync workers.
+#       For the non sync workers it just means that the worker
+#       process is still communicating and is not tied to the length
+#       of time required to handle a single request.
+#
+#   keepalive - The number of seconds to wait for the next request
+#       on a Keep-Alive HTTP connection.
+#
+#       A positive integer. Generally set in the 1-5 seconds range.
