> The code in ProducerPerformance that tries to match a target throughput is
> very inaccurate because it doesn't account for time spent sending messages.
> Since we have to get the current time to timestamp the messages, we can be
> much more accurate by computing the current rate over the entire run and only
> add to the sleep deficit if we're above the target rate.
