>
> 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.
