A production instance is expected to handle a significant workload. By default, the server runs one process and can use only one CPU core for processing, because of the Python language Global Interpreter Lock (GIL). However, a multiprocess mode is available so that concurrent requests can be handled, taking advantage of multiple cores.

The workers=N option sets the number of worker processes to use. As a guideline, you can try setting it to 1+2*P, where P is the number of processor cores. The best setting to use needs to be tuned for each case, as it depends on the server load and what other load-intensive services are running, such as PostgreSQL.

It's better to set workers that are too high for the load than too ...
