|
|
|
|
What is a fast client?
|
|
Generally speaking a fast client is something that is being served over the
|
|
local network or from the same machine. This generally would refer to requests
|
|
forwarded from an upstream proxy. Also see the above FAQ for what a fast
|
|
client is not.
|
|
|
|
What is a slow client?
|
|
A slow client is defined as a request that can take an arbitrary amount of
|
|
time to send a request or read a response. Sometimes due to network
|
|
performance or because it is a malicious client attempting to cause problems.
|
|
Check out the slowloris_ script to generate slow client traffic.
|
|
|
|
What are sleepy applications?
|
|
Applications that expect long request/response times and/or slow clients.
|
|
Gunicorn use `Eventlet`_ or `Gevent`_ to manage concurrency.
|
|
|
|
How might I test a proxy configuration?
|
|
Check out slowloris_ for a script that will generate significant slow
|
|
traffic. If your application remains responsive through out that test you
|
|
should be comfortable that all is well with your configuration.
|
|
|
|
How do I reload my application in Gunicorn?

|
How do I set SCRIPT_NAME?
|

By default ``SCRIPT_NAME`` is an empy string. The value could be set by
|
|
setting ``SCRIPT_NAME`` in the environment or as an HTTP header.
|
|
|
|
How to name processes?
|
|
You need to install the Python package setproctitle_. Then you can name
|
|
your process with `-n` or just let the default. If you use a configuration
|
|
file you can set the process name with the proc_name option.
