There is also a version available at (plug):

  git://github.com/sbober/levitation-perl.git

That is a bit faster and consumes less memory (and is written in Perl).
But that, too, will not be able to handle enwiki at the moment.

levitation does that already.

If desired, I could produce input files for git-fast-import for a larger
wiki (like german or japanese wikipedia), so that other people might
have a look at the performance.
