Tushar Goyal commented on KAFKA-13188:
--------------------------------------
[~aloknnikhil] I am the original author for the code change. We measured the
performance by adding some custom code to measure the performance in
KafkaConsumer. The customization is a follow up PR which was recently merged
here [https://github.com/linkedin/kafka/pull/196]
I can send out a forward port for it.

> Reporter: Lucas Wang

>
>
> Tushar made a [hotfix change|https://github.com/linkedin/kafka/pull/186] to
> the linkedin/kafka repo hosting apache kafka 2.4.
> The change is about releasing memory back to the MemoryPool for the kafka
> consumer, and his benchmark showed significant improvement in terms of the
> memory graduating from Young Gen and promoted to Old Gen.
> Given the benefit, the change should also be added trunk.
