I created a Jira for performance tweaking:
https://issues.apache.org/jira/browse/FLINK-7680
> Add "Performance Tuning" section to docs
> ----------------------------------------
>
> Key: FLINK-7680
> URL: https://issues.apache.org/jira/browse/FLINK-7680
> Project: Flink
> Issue Type: Improvement
> Components: Documentation
> Reporter: Gabor Gevay
> Priority: Minor
> Fix For: 1.4.0
>
>
> We could have a separate section in the docs about performance tuning (maybe
> separately for batch and streaming jobs).
> It could include for example:
> - object reuse
> - serializer issues
> - semantic annotations
> - optimizer hints
> - sorter code generation (Flink-5734)
> See [~fhueske]'s suggestion here:
> https://github.com/apache/flink/pull/3511#discussion_r139917275
