> Key: KAFKA-1115

> Project: Kafka
> Issue Type: Improvement
> Components: producer
> Affects Versions: 0.8

>
> After investigating high CPU usage on some producers in production, we found out that a lot of time was passed in string construction for logging of DEBUG and TRACE level.
> This patch removes most of the logging calls, on our systems it cuts CPU usage down to half of what it used to be.
> Note that this is a significant boost in performance for environment where there are thousands of msg/s.
