# 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.

# serves each request in a thread from an internal thread pool.

# application spends waiting for IO operations and on how much you wish to

# traffic a given process can handle (throughput), but due to CRuby's
# Global VM Lock (GVL) it has diminishing returns and will degrade the
# response time (latency) of the application.
#
# The default is set to 3 threads as it's deemed a decent compromise between
# throughput and latency for the average Rails application.
#
# Any libraries that use a connection pool or another resource pool should
# be configured to provide at least as many connections as the number of
# threads. This includes Active Record's `pool` parameter in `database.yml`.
