# The environment variable WEB_CONCURRENCY may be set to a default value based

# Increasing the number of workers will increase the amount of resting memory
# your dynos use. Increasing the number of threads will increase the amount of
# potential bloat added to your dynos when they are responding to heavy
# requests.

# Starting with a low number of workers and threads provides adequate
# performance for most applications, even under load, while maintaining a low
# risk of overusing memory.
