# - 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.
