I think I read something more precise but I couldn't find it anymore.

Do you have a pointer to documentation or a text that says so? I
see PyPy this way. However, we do have a pypy-c version that works on
Maemo and is more efficient for larger amounts of user objects. We also
have ideas how to reduce RSS size after interpreter startup,
mostly tied to pypy-c so far, though.
In principle it's also possible to translate RPython to C or JVM
and avoid interpretation alltogether. RPython is >50 times faster
than CPython but less convenient to work with than regular Python
so only makes sense to consider for special purposes. And is
probably best learned in collaboration with developers who know
how to work with it and are willing or paid to help.
