It would be interesting to compare the results with fsfs (though
Thorsten didn't specify which back-end was in use).

Exactly. Though such things can easily be part of what you want to put
in the repository.. e.g. MPEG files for game cut-scenes or some other
form of compressed or encrypted data that would be part of a software
project. (Of course use of Subversion is not limited to software
development either.)

Such files though shouldn't add much more to the used disk space than
it would take for a complete copy of the new version of the file. It
certainly shouldn't be storing things as zillions of tiny diffs if it
sees that the result is much larger than the original file size.
