# about methods provided by the DSL, see https://puma.io/puma/Puma/DSL.html.

# 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.
