Tuning worker processes and connections

One of the first limits you'll find with running NGINX at scale is the defaults for the worker processes and connections. At a low level, an NGINX worker process is the dedicated event handler for processing all requests.

The defaults for most NGINX installations are 512 worker connections and 1 worker process. While these defaults work in most scenarios, a very busy server can benefit from adjusting these levels to suit your environment. There is no one-size-fits-all scenario when it comes to the correct values, so it's important to know where you're hitting limits and therefore, how to adjust to overcome them.
