Yeah, it's pretty slow. Part of the problem, I think, is that the
Satoshi peers aren't feeding blocks very quickly, since libbitcoin is
somehow triggering their DDoS protection. Therefore, we only get
blocks at a reduced rate. It would be interesting to wireshark this
and figure out what's actually going on.

One workaround is to setup a Satoshi bitcoind server, and edit it's
bitcoin.conf file to explicitly add the libbitcoin server as a peer.
This doesn't speed things up too much, but it seems to improve
stability a bit.

Even when the blocks come in at a decent rate, there also seems to be
some slowness in the storage backend. It would be interesting to
profile this and figure out what's actually going on. ;)

In the mean time, our approach was to just wait a few weeks for our
first server to sync up with the blockchain. Once we had the first
server running, we rsync'ed the database across to the other servers.
This is crude but effective.
