Since a .pyd file from Pyrex is also from C, the question is ill-posed.
It is equivalent to "Does the C code generated by Pyrex compile to 
faster or slower machine code than the C code generated by some other 
person or program?". Leaving compiler variations aside, the answer 
depend on the proficiency of the other source in relation to the 
particular function being computed. Perhaps you already answered this...

depending on what you meant by 'it'. To be fair, the two code have to 
have exactly the same input/output relationships, including exception
