Consider the following:
mattcm at mourneblade:~$ ls -sk /myth/jenn-20080210.tar.gz 
832984 /myth/jenn-20080210.tar.gz
mattcm at mourneblade:~$ time cp /myth/jenn-20080210.tar.gz  /dev/null

real    0m13.368s
user    0m0.020s
sys     0m1.632s

There was an SD recording from the local frontend going on while this
transfer was occurring, as well.
