Those numbers are pretty close to those in the NetBSD repository, and between them these probably represent just about the most extensive public CVS test data available.
I've only done imports of individual top-level dirs (what used to be modules), like src and pkgsrc, because they're used independently and don't really overlap.
src had about 180k commits over 1M versions of 120k files, 1000 tags and 260 branches. pkgsrc had 110k commits over about half as many files and versions thereof. We too have a few hot files, one had 13,625 revisions. xsrc adds a bunch more files and content, but not many versions; that's mostly vendor branches and only some local changes. Between them the cvs ,v files take up 4.7G covering about 13 years of history.
One thing that was interesting was that "src" used to be several different modules, but we rearranged the repository at one point to match the checkout structure these modules produced (combining them all under the src dir). This doesn't seem to have upset the import at all. Just about every other form of CVS evil has been perpetrated in this repository at some stage or other too, but always very carefully.
