Hi Ismael,
We were previously running on 0.10.2.1 with 8 brokers running around 80%
CPU. But now we have upgraded to 2.3 with 16 brokers. It's the same message
rate, topics, producers and consumers but the CPU is still >80%. How can we

a previous version that used to work, or what, but maybe you're hitting
