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.
