I always start with the assumption that disk seek time is the
bottleneck until proven otherwise, because it is orders of magnitude
slower than any other computer operation and backuppc does a lot of
it.    What else is competing for the head position on those drives?
It can also be on the sending side, especially if you have a lot of
little files and/or applications running concurrently.    It is
possible for CPU/RAM/network to be the problem, but you have to have
done something wrong.
