All,I tried telling maven to use all my cores (8 if you count hyper-threaded cores) and I've seen a 33% reduction in build times. Here's my results:./build.sh clean install -DskipTests 3:43./build.sh clean install -DskipTests -T 4 2:57./build.sh clean install -DskipTests -T 8 2:30I'm using an SSD, so YMMV.However, there are 4 plugins that are not marked as @ThreadSafe, so i'm not sure how safe this is.[WARNING] org.apache.maven.plugins:maven-help-plugin:2.2 (Can't find an issue for this yet)[WARNING] org.codehaus.mojo:buildnumber-maven-plugin:1.2 (Claims to be fixed in 1.2: http://jira.codehaus.org/browse/MBUILDNUM-13)[WARNING] org.codehaus.mojo:xml-maven-plugin:1.0 (Unresolved: http://jira.codehaus.org/browse/MOJO-1709)[WARNING] org.kuali.maven.plugins:properties-maven-plugin:1.5.3 (Unresolved: http://jira.codehaus.org/browse/MOJO-1677)For more info on parallel maven builds:Has anyone else experimented with this feature?Paul.--
