I just tried out a build from the Subversion 1.7.x branch which appears to come close to a final release. Instead of creating
.svn directories everywhere, the new working copy layout switches to a central storage using SQLite. You will only see a single
.svn at the top most directory of the working copy. Details are outlined in the preliminary release notes.
The following is a totally inaccurate benchmark, but I want to share some numbers. The MacPorts repository used here contains lots of directories with only a few files in each, often only a single file. This makes operations walking the
.svn directories in the tree very expensive.
Listing status of files:
~/src/macports/trunk-svn $ time svn st real 3m39.347s user 0m1.450s sys 0m5.900s ~/src/macports/trunk-svn17 $ time svn17 st real 0m23.788s user 0m1.914s sys 0m2.297s
Update without changes (locking the whole working copy against concurrent access):
~/src/macports/trunk-svn $ time svn up At revision 83750. real 2m32.855s user 0m1.202s sys 0m5.060s ~/src/macports/trunk-svn17 $ time svn17 up Updating '.': At revision 83750. real 0m5.362s user 0m1.793s sys 0m1.166s
