This project contains a purposefully flawed hand-written microbenchmark and a corresponding microbenchmark using the Java Microbenchmarking Harness (JMH).
It accompanies a short talk on microbenchmarking at the Software Performance Meetup Group in Munich (Slides).
The project requires at least JDK 8 and Gradle 2.0 or Maven 3.0.
If Gradle is not installed:
git clone https://github.com/danielmitterdorfer/benchmarking-talk.git
cd benchmarking-talk
./gradlew shadow
java -jar build/libs/benchmarking-talk-0.1.0-all.jar
Or alternatively, if Gradle > 2.1 is installed:
git clone https://github.com/danielmitterdorfer/benchmarking-talk.git
cd benchmarking-talk
gradle shadow
java -jar build/libs/benchmarking-talk-0.1.0-all.jar
or finally with Maven:
git clone https://github.com/danielmitterdorfer/benchmarking-talk.git
cd benchmarking-talk
mvn clean package
java -jar target/benchmarking-talk.jar
The Gradle build file supports also IntelliJ IDEA project setup. Just issue gradle idea to create the project files.
