Does anybody know how this compares performance-wise to Numba (http://numba.pydata.org/) which seems like a pretty similar effort? Numba translates to LLVM bytecode rather than C++.
The performance numbers they show are fairly cherry-picked and are not really showing a broad-based comparison of Numba's capability. In addition, Numba is still under active development and the version they used is a few versions older than released. Still it's good to have use-cases and examples which drive Numba improvements.
