I just created a git repository with all branches/tags and full history.
The mirrored .git repository is only ~ 9.4 MB where the svn repository is ~ 42 MB.
The cloned git repository is ~ 31 MB (full history) where the checked out svn repository is ~ 49 MB (one revision).
You can see the advantages of git ...
You can find the git repository here:

Feel free to use it :-)
