If you look at the transfer rates during a copy job to remotes, you see it going down to zero for a short time between files.

While that's understandable from rsync's PoV, it's not as efficient as git-annex could be.

Would parallelization be an option? Are there alternate improvements?

I think that git-annex switching to the P2P protocol for ssh transfers fixed this; it doesn't have the overhead of starting up rsync each time, and even multiple transfers go over the same ssh connection, which also adds efficiency. done --Joey
