Hello,

I have a question about performance testing:

Performance tests for producers can run (using a Java class) with:

bin/kafka-run-class.sh org.apache.kafka.clients.tools.ProducerPerformance

but there is also:
./bin/kafka-producer-perf-test.sh
This is calling a Scala Class called kafka.tools.ProducerPerformance.

Which tool is recommend for 0.8.2.1 and newer?

What are the differences and limitations? I couldn't find anything in the Kafka docs.

They seem to be similar according to the source code.
Is one of the tools deprecated?

Best,

Markus
