Good day, I upgraded a Kafka cluster from v0.8.1.1 to v0.8.2-beta and noticed that the CPU usage on the broker machines went up by roughly 40%, from ~60% to ~100% and am wondering if anyone else has experienced something similar? The load average also went up by 2x-3x.
We're running on EC2 and the cluster currently consists of four m1.xlarge, with roughly 1100 topics / 4000 partitions. Using Java 7 (1.7.0_65 to be exact) and Scala 2.9.2. Configurations can be found over here: https://gist.github.com/mthssdrbrg/7df34a795e07eef10262. I'm assuming that this is not expected behaviour for 0.8.2-beta? Best regards, Mathias
