I'm sitting on a pretty fast connection, and often git-annex isn't using my entire upstream to fill the remotes.
Lets say i have an annex with 10 x 100mb files. and my git-annex has 5 special remotes that needs to be filled.
I would like to have git-annex do 5 concurrent uploads(one to each remote). Currently git-annex only uploads to one special-remote at a time (meaning the 4 remaining servers are just waiting).
It would also be nice to have a per remote number of threads. Especially if adding a directory with 1000 small files in it(say 100bytes each), having 5 transfer threads to each remote would make the sync complete much faster.
