Hi John, It looks like representation sharing works particularly well for your repository. http://subversion.apache.org/docs/release-notes/1.6.html#rep-sharing The 30% reduction you're seeing is a pretty nice space savings. Do you do a lot of branching? Do you have the identical files comitted separately to different parts of the repository? // Ben
