performance regression with 0.10.2.0 client talking to 0.10.0.1 servers
I noticed a significant reduction in throughput when I upgraded my app to 0.10.2.0. I am talking to 0.10.0.1 server and I wanted to take advantage of the compatibility of the newest release with old server, but I noticed that my performance went from 20K msg/sec to 2K msg/sec in one case and from 9K msg/sec to 4K msg/sec in another case.
Is this expected or should I file a bug?

Sorry, after a second look, that PR only fixes a cosmetic issue, it
shouldn't be the reason for the performance issue you are seeing.

Hi Alex,
Yes, please file a JIRA and include as much detail as possible: configs
used by the broker and producer/consumer (it wasn't clear which had the
issue), message size and a sketch of what the code is doing and what is
being measured.
Thanks,
Ismael
