Resolution: Fixed
> AsyncKafkaConsumer has higher than expected CPU usage
> -----------------------------------------------------
>
> Key: KAFKA-20904
> URL: https://issues.apache.org/jira/browse/KAFKA-20904
> Project: Kafka
> Issue Type: Bug
> Components: clients, consumer
> Reporter: Evan Zhou
> Priority: Blocker
>
> We run scheduled tests of the Consumer to compare perf metrics between the
> `classic` and `consumer` protocols, and recently noticed CPU usage has
> doubled for the `consumer` protocol.
> https://github.com/apache/kafka/pull/22979 seems to be the suspect based on
> tracking down the commits made in between test runs, but more investigation
> is needed to figure out why this change caused such a big increase in CPU and
> what the correct fix is
