Chen He commented on KAFKA-2499:
--------------------------------

Does Kafka-3554 resolve this problem? User can control the compression ratio.

> ProducerPerformance.scala (There are two of these, one used by the shell script and one
used by the system tests. Both exhibit this problem)
> creates messags from empty byte arrays. 
> This is likely to provide unrealistically fast compression and hence unrealistically
fast results. 
> Suggest randomised bytes or more realistic sample messages are used. 
> Thanks to Prabhjot Bharaj for reporting this.
