Re: PyPy (it work's !)

Hi Ruben,

I'm still very much interested in Pypy + Odoo so it would be great if you have time to look into lxml cffi !

BTW, you asked about memory usage of Odoo + Pypy. Well, I have bad news for this one: Pypy uses much more memory than cpython (2-5 times...).
I don't have any idea why it is like this, and to investigate we need jit aware profiling so we need Odoo + Pypy 2.6, so we need lxml cffi...

Hi Nicolas,

I'm terribly sorry for the late reply. I only noticed your e-mail today
(it disappeared in a long bunch of other Odoo mails).

It's pretty coincidental, but I'm getting into CFFI next week, because
I'm rewriting a Python script as a C++ module.

If people are still interested in PyPy + Odoo, I could have a look into
the lxml cffi versions after I rewrote npTDMS in C++.
