That should be fine, but it doesn't have any way of reporting stats
currently.  You could use tools like ifstat to look at how much
bandwidth you are using.  You can also look at how much cpu the swift
tool is using.  Depending on how your data is setup, you could run
several swift-client processes in parallel until you max either your
network or cpu.  I would start with one client first, until you max it
out, then move on to the next.
