Subject Re: Which perf-test tool?
Date Wed, 23 Sep 2015 11:51:03 GMT
Both classes work ok. I prefer the Java one simply because has better output and it does less
overriding of default values.

However, in both cases you probably need to tweak settings to suit your use case. Most notably:

acks
batch.size
linger.ms
based on whether you are interested in latency or throughput. That is usually sufficient for
producer performance measurement. 

At present nothing is deprecated but there are some changes going in to clean these up a little.
