## Ratelimiting ##
|
|
|
|
# Ratelimiting settings for client actions (registration, login, messaging).
|
|
#
|
|
# 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 messages that ratelimits sending based on the account the client
|
|
# is using
|
|
# - 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.
|
|
# - one for ratelimiting redactions by room admins. If this is not explicitly
|
|
# set then it uses the same ratelimiting as per rc_message. This is useful
|
|
# to allow room admins to deal with abuse quickly.
|
|
# - two for ratelimiting number of rooms a user can join, "local" for when
|
|
# users are joining rooms the server is already in (this is cheap) vs
|
|
# "remote" for when users are trying to join rooms not on the server (which
|
|
# can be more expensive)
|
|
# - one for ratelimiting how often a user or IP can attempt to validate a 3PID.
|
|
# - two for ratelimiting how often invites can be sent in a room or to a
|
|
# specific user.
|
|
#
|
|
# The defaults are as shown below.

|
|
#
|
|
# The rc_federation configuration is made up of the following settings:
|
|
# - window_size: window size in milliseconds
|
|
# - sleep_limit: number of federation requests from a single server in
|
|
# a window before the server will delay processing the request.
|
|
# - sleep_delay: duration in milliseconds to delay processing events
|
|
# from remote servers by if they go over the sleep limit.
|
|
# - reject_limit: maximum number of concurrent federation requests
|
|
# allowed from a single server
|
|
# - concurrent: number of federation requests to concurrently process
|
|
# from a single server
|
|
#
|
