As a general rule of thumb, the code generated by Cython is quite a bit
longer and substantially faster than the corresponding Pyrex code.

The increase in code size is due to a general preference for speed, as many
Cython developers use it for highly performance critical stuff like number
crunching. It's not only faster for algorithmic code, though, it's also a
lot faster for thin wrapper code and even for pure Python code. And it runs
a substantial part of the CPython test suite by now.
