Hi, I am trying to measure throughput of my 3 broker kafka cluster. I have created a topic with 3 partitions spread equally over the 3 brokers. Run a producer application to produce messages. producer application has 3 thread (one for each partition) to produce. Then i increased the number of partitions in the topic to 6. partitions are equally distributed among the brokers (2 per broker). Increased the number of threads in the producer to 6 (one for each partition). I expected the throughput to approximately double but what i observed is, throughput remained same and latency has almost doubled. Any suggestion/lead why latency has doubled causing the throughput to be almost same as previous one ?
