I'd recommend to use the default value until you have an evidence that
the default value needs to be tweaked.  All other numbers need to
be tested pretty well with the same traffic volume and pattern.

Please note that the worker_connections is the number of sumiltaneous
connections per worker.  The configuration file you've shared contains
the following line:

  worker_process auto;

So, the number of worker process depends on a number of CPUs in the
system.

Hope that helps.
