400 Mb, right?

I think, if you add such functionality the cache advantage will almost gone.

You can implement something outside of Py++/pygccxml
    - "unzip" before passing to py++
    - zip after code generation was done.

Thus you will get the time measures. If they are good I will be glad
to work with you to integrate this functionality to Py++/pygccxml.

It could be nice if you describe in few words how you are going to do
this, so we could close the interface only once :-).

Thanks
