I do think this is an artefact of your contrived test.

An fsfs conversion of a 2.6GB CVS repository has resulted in a 2.0GB
SVN repository of 25,000 revisions.

Assuming commits are typically not single-file one-liners, we expect
this trend to continue (though our rate of revisions will increase as
we move to more branching and merging).
