I have got one repository with 11495 files. These repository consists of jpeg, ttf, png and pdf file types. All files are binary.
I have done some benchmark with git and svn:
git clone (remote,ssh) : 38m49.516s
svn checkout (remote,ssh) : 48m20.330s
Size, after git clone : 23G
Size, after svn checkout : 24G
Size, only files without revision control: 12G
git status : 0m0.634s
svn status : 0m0.654s
