How about looking for subtasks that could be parallelized beneath the
build-task, i.e. compile, assembly, package, report generation, and
other Maven plugin tasks. These tasks will not have an impact on the
local repository, but are still resource-intensive (especially javadoc
generation) . Many of these are serial dependent within one build, but
compilation in x different projects, for instance, are not. This could
boost performance of building multiple projects, but would require some
synchronization between builds when it comes to install and dependeny
resolution. Well, this is maybe more a Maven thing, than Continuum.

By the way, the maven-compiler-plugin support a fork av a jvm, and this
will be executed in a thread of its own. Have anyone got experiences
with this and performance?

Most servers used today have multi-core cpus or even multiple cpus. If
you have 2 quad-core cpus, there is a potential of running 8 parallel
threads.=20

The potential issue with a single local repo with a parallel build is if
two build try to download or install the same artifact in it.
