Jesse Glick commented on Improvement JENKINS-15120

Retesting with svn up for both builds (originally the first used co), and with verbose logging turned off in the branch. Trunk builds takes 6:02 min (of which the Maven build itself was 1:26):

Loading Type Time (s) Count
Classes 243.2 3320
Resources 2.6 26

I tried to run the branch build again but this time it failed with a java.lang.OutOfMemoryError: PermGen space (on the master) which is disconcerting; did the branch introduce some kind of class loader leak?

I retried it, this time succeeding in 4:10 (Maven build 1:06):

Loading Type Time (s) Count
Classes 141.0 3323 (prefetch cache: 1633)
Resources 2.2 26

So that is a 31% reduction in build time, which I would say is pretty good.

BTW using https://svn.codehaus.org/mojo/trunk/mojo/nbm-maven as the test project, more or less arbitrarily. Intentionally using a native Maven project since that puts far more load on the remoting layer than a freestyle project.
