JiminHsieh commented on KAFKA-1623:
-----------------------------------
Can I work on this one? Thanks! I have some ideas for previous comments. I
didn't have a good idea about 500ms waiting time though, I am working on it,
but I think we could give a default value for the backlog by OS instead of the
default value of JDK - 50. At Linux and macOS, it will be 128 At Win, it will
be 200.

> Key: KAFKA-1623
> URL: https://issues.apache.org/jira/browse/KAFKA-1623
> Project: Kafka
> Issue Type: Bug
> Components: core
> Affects Versions: 0.10.1.0
> Reporter: Shlomi Hazan
> Priority: Major
> Labels: performance
>
> from SocketServer.scala:144
> the Acceptor can wait up to 500 millis before processing the accumulated FDs.
> Also, the backlog of the acceptor socket seems not to be defined, which may
> be problematic if all 500 millis are elapsed before the thread awakes.
> setting the backlog is doable using the proper ServerSocket Ctor, and maybe
> better be provisioned via configuration.
