Yes I have been looking at some benchmarks, a few weeks ago. In
benchmarks measuring object creation, MacRuby is slower because
allocating an object in vanilla Ruby is cheap. On the other side, GC
cycles seem to be faster.

But it's definitely early to compare performances yet. And there are a
few things we can do in MacRuby to improve allocations, and more.
