I've done a certain amount of tweaking CVS performance, and the time
involved in applying deltas does not dominate. The big performance
bottlenecks are (1) figuring out what files to operate on. I would
guess that by now this has been tweaked in CVS to the point where
fairly fundamental changes (which are not out of the question) will be
needed for further improvements, and (2) getting to the point of being
ready to actually apply deltas for a particular file. In the current
implementation, this requires way too much fork/exec and other system
calls, and could be improved a lot in relatively straightforward ways.
Incidentally, Cyclic (a CVS support company, see
http://www.cyclic.com) is starting to look at the Ada market. If
anyone has any particular opinions they would like to share about what
the Ada community wants from configuration management, I'd be
interested in knowing them (by email please; post the message as well
if you so desire).
