I am guessing here, but I think one of the factors (don't know how big
of a factor it is) is the number of files in the repository and number
of branches/tags.
In CVS, for each tag/branch, every file that is part of the tag/branch
will get an entry in their respective RCS file. Whereas in SVN a
branch/tag is one small file representing a link.
