I have a small benchmark program doing tight binding calculations of carbon nanostructures that I have implemented in C++ with Eigen, C++ with Armadillo, Fortran, Python/numpy, and Julia. It's been a while since I've tested it but IIRC all the other implementations were about on par, except for python which was about half the speed of the others. Haven't tried with numba.

To bring Julia performance on par with the compiled languages I had to do a little bit of profiling and tweaking using @views.
