Finally some interesting numbers, and if (heaven forbid) this decision
should be based on
technical grounds, this is one of the first significant pieces to come
up in this discussion.

Since I am quite unfamiliar with logging (I use loose coupling and
tests instead ;), I took the opportunity to read
http://logging.apache.org/log4j/2.x/performance.html Somehow the
real-life results don't seem to match up with the advertising blurp on
the log4j site. While it hardly surprises me, I was wondering if
anyone actually knows why?
