More than happy to run the tests, although if you don't provide an iOS project for them, I'd probably have to, and there are a lot of variables (compiler configuration) at play.

We do a lot of 3D point cloud data manipulation. I'm not sure how much of it relies on Eigen, and how much is in Boost or OpenCV, but currently this processing is the bulk of our user wait time.

I'm not sure if profiling the code would could tell us how much time is spent in Eigen, given the template nature of the code? In any case, I don't actually write that processing code, that's other guys on the team. I just integrate it into our iOS app.
