Sonatype Maven Shell and Parallel builds in Maven 3

Today I played around with the parallel build feature from Maven 3 and with the sonatype maven shell. The sonatype maven shell is based (required) on Maven 3. Here my first build performance results.

	Maven 3	Maven 3 (mvn -T 10)	Maven 3 (mvn -T 1.5C)	Maven Shell
mvn clean compile	ca. 5 sec	ca. 3 sec	ca. 4 sec	ca. 2 sec
mvn clean package	ca. 12 sec	ca. 10 sec	ca. 10 sec	ca. 7 sec
mvn package	ca. 7 sec	ca. 6 sec	ca. 6 sec	ca. 3 sec
mvn clean site	ca. 4 min	ca. 4 min	ca. 4 min	crashed
mvn javadoc:javadoc	ca. 56 sec	ca. 29 sec	ca. 29 sec	ca. 27 sec
