The problem is that when I do a compile, it never makes use of more than six CPUs. In otherwords, there are never more than six things being compiled at once. Since everyone sees this effect, and at all times, I'm wondering if it is some built-in rate limit in either distcc, Xcode's version of distcc, or Xcode itself. Anyone have a clue?


Mark,

The following command in terminal will change the max number of distributed tasks to 16... although you get diminishing returns after a certain point.. (somewhere around 12 is what I found) Play around & find what's best.


defaults write com.apple.Xcode XCMaxNumberOfDistributedTasks 16
