------------------------------------
The best place to learn more about using JMH is the [Sample
Benchmarks|http://hg.openjdk.java.net/code-tools/jmh/file/tip/jmh-samples/src/main/java/org/openjdk/jmh/samples/].
> Use JMH for Log4j2 performance tests
> ------------------------------------
>
> Key: LOG4J2-654
> URL: https://issues.apache.org/jira/browse/LOG4J2-654
> Project: Log4j 2
> Issue Type: Improvement
> Affects Versions: 2.0-rc2
> Reporter: Remko Popma
> Assignee: Remko Popma
> Fix For: 2.0-rc2

> I've been using JMH (http://openjdk.java.net/projects/code-tools/jmh/ ) for
> performance tests recently and I'm very impressed. JMH is developed by the
> Oracle java performance team and used internally by Oracle to performance
> tune the JVM and java core libraries.
> I would like to use JMH to start building a suite of performance tests for
> log4j2.
> I propose adding a log4j-perf module. This is where our performance test code
> would live. JMH microbenchmarks are very simple java classes with
> org.openjdk.jmh annotations. During the build, JMH generates code and that
> generated code, together with all dependencies are zipped up in a large
> uber-jar with the maven Shade plugin. You can then use java -jar
> microbenchmarks.jar to run performance tests.
> JMH is released under the GPL v2 license (incompatible with the Apache
> License v2) so we need to be careful not to include the generated
> microbenchmarks.jar or any other GPL files in the log4j distribution.
