Code Tools : JMH JDK Microbenchmarks

The JMH JDK Microbenchmarks is a collection of microbenchmarks for measuring the performance of the JDK API and JVM features using the JMH framework.

Building and running the project

Currently, the project can be built and run with JDK 8 and later. This is a Maven project and is built by:

$ mvn clean install

After building, the executable jar is target/jmh-jdk-microbenchmarks-[version].jar. Run the benchmarks with:

$ java -jar target/jmh-jdk-microbenchmarks-*.jar [optional jmh parameters]

See the entire list of benchmarks using:

$ java -jar target/jmh-jdk-microbenchmarks-*.jar -l [optional regex to select benchmarks]

For example:

$ java -jar target/jmh-jdk-microbenchmarks-1.0-SNAPSHOT.jar -l .*bulk_par_lambda.*

And the same regex syntax works to run the same set:

$ java -jar target/jmh-jdk-microbenchmarks-1.0-SNAPSHOT.jar .*bulk_par_lambda.*
