Restoring is much too slow to be explained by bandwidth. My worst restore 
took several days and used less than 1% of available bandwidth.

Single-file restores are fast (at least fast enough not to irritate me). I 
think the problem is that that requests aren't pipelined. The client asks 
for a file, the server retrieves the file from the storage backend, the 
file is transferred, the client writes it to the file system, the client 
thinks about what file to ask for next, GOTO 1. If you're restoring half a 
million small files the network connection will be idle a lot of the time.

Life is much better if you restore a single big file (and even better if 
you don't have to restore).
