The basic approach usually as far as I know is to set worker_processes based
on your CPU core count (either identical or sometimes there is benefit
setting with some multiplier - 2*cores (I have seen some improvements when
using nginx as on-the-fly image resizer to utilise the box more)).

worker_connection - typical 1024 or 2048 usually is enough. Bassically the
math is based on max_clients where: max_clients = worker_processes *
worker_connections

Anyways nginx should complain in error log if the settings are too low and
all the workers are exausted (like you have thousands of keepalive/active
connections).


The same with FPM - the basic settings which come with the sample config
should be enough. If you leave the default notice error level log FPM should
tell you if all of the php pool is fully used and there is a need to
increase the setting.

So in short - both of the software products are clever enough to tell you
what could be the optimal setting for you based on the workload of the box.


p.s. remember also to tweak other system settings - like maximum open file
descriptors, tcp port range etc
