+To speed up the build you can:
+- use the build-in "fast" maven profile which will skip unit tests, integration tests, QA plugins, and JavaDocs.
+- active maven parallel build, e.g. "mvn -T 1C" means 1 thread per cpu core.
 
+The build script will be:
 ```bash
-mvn clean install -DskipTests -Dfast
+mvn clean install -DskipTests -Dfast -T 1C

Review comment:
