I think the main point of John's email is that we should update the Sage Programming guide with the remarks you make above. Is that right John? 15 minutes for a first clone is very very very weird though. It's just copying a bunch of files. Maybe something else was going on with your computer, e.g., os x was building some spotlight index or something...
