Mac Pro Westmere XCode C++ Build
This test builds diglloydTools (C++) using an Automator script.
Developers using Apple XCode can rejoice at shorter build times, but XCode does not scale perfectly, even with a triple-SSD RAID=0 stripe. Times shown are second build, a hair faster than the first build.
CPU usage is near the max for most of the build, but there is some kind of serialization part-way through, which reduces the 12-core advantage.
