 5. Another reason why I appear to be forced to use "unlocked" mode is that, as part of the mirroring, the directory permissions are set to match the site, which are not writable.  git-annex appears to be unable to move the files that are inside of directories without write permissions.  Note that I am the owner of the local files/directories, and lftp happily adds and modifies files insides of these unwritable directories just fine, presumably by temporarily changing the permissions.  Is this correct?  Should I submit a feature request here?
 
-5. Although I am using WORM and unlocked mode, I found the initial "git add" and "git commit" of the 10K / 30GB of files to be pretty slow.  It takes on the order of 30 minutes for the add and an hour for the commit.  I didn't see a ton of either CPU or I/O activity.  Is this to be expected?  I would have hoped that the WORM backend prevents git from needing to actually read the files for a checksum.  (I'm hopeful that with the WORM backend, subsequent add and commits will be a lot faster.)

It takes on the order of 30 minutes for the add and an hour for the commit.  I didn't see a ton of either CPU or I/O activity.  A subsequent update of about 600 files is taking a long time to add (running 'git add -A'.)  I assume commit time will also be long.  Is this to be expected?  I would have hoped that the WORM backend prevents git from needing to actually read the files for a checksum.
 
 6. I understand that "thin = false" will lead to data duplication.  I assume this will make the initial commits slower.  Are there other performance implications of changing the thin setting?
