I think the numbers are realistic and this issue comes up now and then. What
you missed is the fact that the checkout operation doesn't matter, because
typically a working copy is a long-lived thing, i.e. you do it once you start
working on something and (possibly months later) delete it. What really
matters are operations like diffing, updating and committing, which is where
SVN is superior to CVS, both in terms of bandwidth consumptions (and thus
speed) and reliability.
