Test Eclipse 3.6.1, CDT 6 bake
================================= ================================= =====================================
Build whole workspace 13:01 min 7:19 min
Rebuild without clean 3:05 min 0:50 min
Clean whole workspace 0:41 min 0:08 min
Clean the cleaned workspace 0:35 min 0:02 min
================================= ================================= =====================================
.. note::
For the build `Eclipse` needs additional `300 MB of RAM`, in contrast `bake` takes up `35 MB` of RAM at it's peak.
