David Mao updated KAFKA-10673:
------------------------------
Description:
ConnectionQuotas.protectedListener calls `config.interBrokerListenerName`. This
is a surprisingly expensive call that creates a copy of all properties set on
the config. Given that this method is called multiple times per connection
created, this is not really ideal.
Profile attached showing allocations in `protectedListener`
was:

Profile attached showing allocations. Allocations in Acceptor.run() made up 2%
of the allocations on a fairly busy cluster.
