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 |
