> It would be helpful to measure rebalance time separately in the performance tool so that
throughput between different versions can be compared more easily in spite of improvements
such as https://cwiki.apache.org/confluence/display/KAFKA/KIP-134%3A+Delay+initial+consumer+group+rebalance.
At the moment, running the perf tool on 0.11.0 or trunk for a short amount of time will present
a severely skewed picture since the overall time will be dominated by the join group delay.
