Of course, in real life your modules do not take equal amounts of time. Significant gains are common when the project has one or more "api" modules and dependencies on the "api" modules (and just bring the "impl" version of the module into the actual assembly that will be started). This design normally means your big chunky modules depend on lightweight "api" modules that build quickly.

The parallel build feature rewards "correct" modularizations. If your project has degenerated inter-module dependencies (execessive dependencies inside reactor), you will probably see gains by cleaning up the dependencies.
