The reason for studying it is that I have a large CVS project, which
requires SSH access over the net to a remote server where it takes 10
minutes to do all the "cvs update" operations. People are nagging about
that, i.e. I needed to see of e.g. Subversion is faster or not.

See above :)

Point taken,
I know CVS quite well, but I have no "darling". Subversion has some good
properties (by design) so it is obvious to analyse that.
Also thanx to Michael Haggerty - I can comment later on his postning.
