----------------------------------
Summary: 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.
