Remko Popma commented on LOG4J2-1395:
-------------------------------------
Yes, I'm okay to merge this into master.
The key benefit of this option is the performance improvement, so I think this
should be mentioned on the Performance page somehow.
Shall we add a new section "Console logging" under the [Which Log4j 2 Appender
to Use?|https://logging.apache.org/log4j/2.x/performance.html#tradeoffs]
section?
It would be good to have a graph that shows the main point: *if you redirect to
a file, then the "direct" console option is a lot faster than the normal
console (but not as fast as the file appender)*. So perhaps a graph that
compares Console to DirectConsole to FileAppender for a number of threads. (We
can get the data from running the JMH Log4j2AppenderComparisonBenchmark for
appenderConsole, appenderDirectConsole and appenderFile with a range of
threads.)
