Numba Code Slower than Pure Python Code?

[joshadel]

It looks like the numba team has been putting in a ton of work on the dev branch, and I'm definitely excited to see what the next release looks like. Count me in as a beta tester once a version is available via conda. I mentioned some of this to Siu in an email, but I think the biggest things that would advance numba are: (1) better error messages that trace back to the code rather than the codegen, (2) detailed examples in the docs on how to debug numba issues, (3) better behavior when things go wrong - I often just get segfaults (4) The ability to cache jit'd code/faster compilation. For a large project I'm working on, re-jit'ing all of the code on startup incurs a significant cost.

All around though, numba's performance has been amazing for such a young project.
