Subject Increased CPU usage with 0.8.2-beta
Date Mon, 08 Dec 2014 09:25:50 GMT
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:

I'm assuming that this is not expected behaviour for 0.8.2-beta?

Best regards,
