---------------------------------------------
Summary: producer performance affected by trace/debug calls
Key: KAFKA-1115
URL: https://issues.apache.org/jira/browse/KAFKA-1115
Project: Kafka
Issue Type: Improvement
Components: producer
Affects Versions: 0.8
Reporter: Francois Saint-Jacques
Assignee: Francois Saint-Jacques
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.
