You will find the slides in src/main/resources as plain text files in German.
The demo code is located in src/main/java, and the whole project is generated and run by Maven.
The JMH benchmarks require a generation run first:
mvn clean install && java -jar target/benchmarks.jar -i 5 -wi 5 -f 1 ".*"

I assume the "slides" and "code" alone do little for you without my talking, but if you want to use an example "as-is", please reference me and allow others to reuse your examples as well. I am not applying any specific "code-license" because I think it is unlikely anybody would want to use this code as library :-)
