About Cython

[Cédric Krier]

Hi,

Following this request [1], I was wondering of someone had some
experience about Cython. Do you think Cython support will improve
python-sql? Because my quick test doesn't seem to show any improvement
(simple convertion to C and running the tests).

Hi Cédric,

I've tried to make some code partial rewritten with "cdef",
but sadly it becomes more slow(I guess it make some convert between C String <-> Python String type

I'll keep trying about this rewrite work, maybe write all the code which use the String operations...

BTW, is there any repository of this project on the Github?
It seems more convenient to do code review & make new forks...:P

Yes python-sql is mainly about concatenating strings so I don't know if
Cython is relevant.

It will be great to show your work.

No.

You can create a clone at

I think if we try to improve python-sql performance we need a common
benchmark to measure improvements.
So I write this simple script that uses timeit.
What do you think?
