I actually did a talk about logging performance. The repo with the code https://github.com/corneil/logging-is-not-free
The bottom line is that the logger.info() will be faster if you are always using info level but logger.info{} is a lot better if you're loglevel is warn or error. So I always use lambda for info and debug since they may be ignored.
