I know CVS can do compression, but it doesn't do it by default, does it?  By that
I mean that I see speedups of an order of magnitude when I add "-z 9" to the cvs
command line.

If CVS isn't compressing on any given connection, what's wrong with using SSH
compression for that connection?  Presumably it's the same CPU compressing the
same data, anyway...

I don't know enough about CVS to answer this:  is there some inherent advantage to
having CVS compress the data?
