Jun Rao commented on KAFKA-176:
-------------------------------
1. It can be in the code. Maybe we just need a command line option to control
whether to display header or not?
2. I am suggesting that we alway show aggregated output. So there won't be a
-aggregate option. Instead, have a --showDetails option to enable/disable
detailed stats in each thread, probably with default set to false.
3. Some system tests can use a producer that generates variable-sized random
messages. Instead of having another producer tool, it would be good if we can
just allow such option in this tool.

> 2. fix the bugs, so that they measure throughput correctly
