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,
