## Ratelimiting ##
# Number of messages a client can send per second

#rc_messages_per_second: 0.2
# Number of message a client can send before being throttled
#
#rc_message_burst_count: 10.0
# Ratelimiting settings for registration and login.
#
# Each ratelimiting configuration is made of two parameters:
# - per_second: number of requests a client can send per second.
# - burst_count: number of requests a client can send before being throttled.
#
# Synapse currently uses the following configurations:
# - one for registration that ratelimits registration requests based on the
# client's IP address.
# - one for login that ratelimits login requests based on the client's IP
# address.
# - one for login that ratelimits login requests based on the account the
# client is attempting to log into.
# - one for login that ratelimits login requests based on the account the
# client is attempting to log into, based on the amount of failed login
# attempts for this account.
#
# The defaults are as shown below.
#
#rc_registration:
# per_second: 0.17
# burst_count: 3
#
#rc_login:
# address:
# per_second: 0.17
# burst_count: 3
# account:
# per_second: 0.17
# burst_count: 3
# failed_attempts:
# per_second: 0.17
# burst_count: 3
# The federation window size in milliseconds
#
#federation_rc_window_size: 1000
# The number of federation requests from a single server in a window
# before the server will delay processing the request.
#
#federation_rc_sleep_limit: 10
# The duration in milliseconds to delay processing events from
# remote servers by if they go over the sleep limit.
#
#federation_rc_sleep_delay: 500
# The maximum number of concurrent federation requests allowed
# from a single server
#
#federation_rc_reject_limit: 50
# The number of federation requests to concurrently process from a
# single server
#
#federation_rc_concurrent: 3
# Target outgoing federation transaction frequency for sending read-receipts,
# per-room.
#
# If we end up trying to send out more read-receipts, they will get buffered up
# into fewer transactions.
