David Mao updated KAFKA-10673:
------------------------------
Description:
!Screen Shot 2020-11-03 at 8.34.48 PM.png! 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. Allocations in Acceptor.run() made up 2%
of the allocations on a fairly busy cluster.
