Btw, does anybody know roughly how much data a initial "cvs co" takes on
the mozilla repo? Git will obviously get the whole history, and that will
inevitably be bigger than getting a single check-out, but it's not
necessarily orders of magnitude bigger.

339MB for initial checkout

And I think people run :pserver: with compression by default, so we're
likely talking about half that in actual download overhead, no?

Yes, most people have -z3, and I agree with you, on paper it sounds
like the cost is 1/4 of a git clone.

However.

The CVS protocol is very chatty because the client _acts_ extremely
stupid. It says, ok, I got here an empty directory, and the server
walks the client through every little step. And all that chatter is
uncompressed cleartext under pserver.

So the per-file and per-directory overhead are significant. I can do a
cvs checkout via pserver:localhost but I don't know off-the-cuff how
to measure the traffic. Hints?

cheers,
