> (through Cython)

My personal experience is that you can actually get another factor of 2 or 3 speed-up by ditching Cython and using actual C instead (I think it's because optimizers have a hard time cleaning up the C that Cython produces), even if you've turned off thing's like bounds checking.

I meant "through Cython" as in "passing through Cython", ie, Cython is just a thin wrapper layer over the real C/C++ code.
