Jason Gustafson commented on KAFKA-5358:
----------------------------------------
[~huxi_2b] It seems like the discussion thread on the dev list has died down.
So perhaps it is time to start a vote (also on the dev list)?
> Consumer perf tool should count rebalance time separately

> 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.
