I’m running builds via an overburdened TeamCity cluster using gradlew. As you might of guessed (I’m involved), we’re pulling some nontrivial stunts with Gradle (eg: https://github.com/RobertFischer/Gradle-License-Report). Builds were taking an average of 8m13s, and after upgrading to Gradle 1.8 from 1.6, they dropped to averaging 6m58s. Nice! Thanks!
