+Another expensive thing sync has to do, due to the adjusted branch
+being checked out, is Command.Sync.updateBranches. In my repo with 10000
+files, when not using --content, that is responsible for most of the run
+time of a sync when there is nothing new to import or pull.
+
+It should be possible for sync to avoid running that when it didn't pull
+any changes that need to be propagated back to the parent branch from the
+adjusted branch.
+
+With the master branch checked out instead, `git-annex sync --content` is
+now as fast as `git-annex find --not --in source`.
