> --------------------------------------------------
>
> Key: KAFKA-1563
> URL: https://issues.apache.org/jira/browse/KAFKA-1563
> Project: Kafka
> Issue Type: Bug
> Affects Versions: 0.8.1.1
> Reporter: Fedor Korotkiy
>
> On our kafka cluster with 3 brokers and input 40MB/s we see about 100K
> packets/s traffic between brokers(not including consumers). Majority of
> packets have small size(about 20bytes of data).
> I have found that kafka server sets TcpNoDelay option on all sockets.
> https://github.com/apache/kafka/blob/0.8.1/core/src/main/scala/kafka/network/SocketServer.scala#L202
> And I think that causes the issue.
> Can you please explain current behavior and fix it/make it configurable?
