I just bought a new Mac Pro to use because my Macbook Pro has a clean build time of around ~50 minutes on my app. I was hoping that the Mac Pro would significantly improve this, however it is in fact many times *slower* than the Macbook Pro, clocking in around 3-4 hours from a clean build.
I have noticed in the activity monitor that there are many "clang" processes at around 50% CPU each, and the overall CPU load doesn't go above 50%, with 50% idling. Here is a screenshot: http://imgur.com/a/UP6qt
Any insight as to why this might be would be really appreciated.
