jmh-benchmarks

This project contains several micro-benchmarks to stress specific points of the my compilation and runtime strategies.

Building

This Maven project builds a self-contained executable Jar file in target/:

$ mvn clean install

It uses the OpenJDK JMH benchmark harness.

We tend to be on the bleeding-edge of JMH, so you may need to build yourself a local copy from a Mercurial checkout:

$ hg clone http://hg.openjdk.java.net/code-tools/jmh/ jmh
$ cd jmh/
$ mvn clean install -DskipTests=true

Running

JMH-produced executable Jars support many options, so list them all:

$ java -jar target/microbenchmarks.jar --help

A typical execution could look as follows:

$ java -jar target/microbenchmarks.jar -f 1 -w 2s -r 2s
