2k msgs/s is silly, unless your messages are 10MB each, so something is
clearly wrong.

* What is the CPU usage and IO load when running your performance tests?
* Are you using the sync producer per chance? Maybe combined with an
aggressive log.flush.interval?
* For reference, and to find out where the bottleneck is, try running
rdkafka_performance [1] according to the previous link I posted:
  if performance does not increase then the broker is the problem,
otherwise it is the producer/consumers.
