# This number should be, at maximum, the number of CPU cores on your system. 
# (since nginx doesn't benefit from more than one worker per CPU.)
worker_processes 8;
 
 
# Determines how many clients will be served by each worker process.
# (Max clients = worker_connections * worker_processes)
# "Max clients" is also limited by the number of socket connections available on the system (~64k)
# run ss -s  and u'll see a timewait param
# The reason for TIMED_WAIT is to handle the case of packets arriving after the socket is closed.
