+I don't think that git-annex is doing anything particularly slow with the
+bup special remote. Other than actually running bup, that special remote
+should run about as fast as other similar special remotes, like say
+the directory special remote.
+
+So, this is probably a performance problem in bup. Now, git-annex does
+use bup in an unusual way, running one bup-split per file to store in it.
+That was the only way to shoehorn what git-annex needs to do into bup
+though.
