This resource bound assumption is why we require a buffering proxy in front of a default configuration Gunicorn. If you exposed synchronous workers to the internet, a DOS attack would be trivial by creating a load that trickles data to the servers. For the curious,Slowlorisis an example of t...
The default synchronous workers assume that your application is resource bound in terms of CPU and network bandwidth. Generally this means that your application shouldn’t do anything that takes an undefined amount of time. For instance, a request to the internet meets this criteria. At some poin...

To ensure the workers are still alive, Gunicorn has a heartbeat system—which works by using a file on the filesystem. Gunicorn therefore recommends that this file be stored in a memory-only part of the filesystem. As the Gunicorn FAQ explains, the default directory for the heartbeat file...
Gunicorn, as we have discussed, offered the possibility to work with various type of workers. For the majority of deployments, the standard worker type - sync - will be sufficient and comes by default, therefore not requiring any explicit setting. ...
Workers silent for more than this many seconds are killed and restarted. Value is a positive number or 0. Setting it to 0 has the effect of infinite timeouts by disabling timeouts for all workers entirely. Generally, the default of thirty seconds should suffice. Only set this noticeably higher...
