# Puma can serve each request in a thread from an internal thread pool.
# The `threads` method setting takes two numbers: a minimum and maximum.
# Any libraries that use thread pools should be configured to match
# the maximum value specified for Puma. Default is set to 5 threads for minimum
# and maximum; this matches the default thread size of Active Record.

# Specifies the `worker_timeout` threshold that Puma will use to wait before
# terminating a worker in development environments.
#

# Specifies the `port` that Puma will listen on to receive requests; default is 3000.

  # Specifies the number of `workers` to boot in clustered mode.
  # Workers are forked webserver processes. If using threads and workers together
  # the concurrency of the application would be max `threads` * `workers`.
  # Workers do not work on JRuby or Windows (both of which do not support
  # processes).

  # Use the `preload_app!` method when specifying a `workers` number.
  # This directive tells Puma to first boot the application and load code
  # before forking the application. This takes advantage of Copy On Write
  # process behavior so workers use less memory.
