To reinforce Karl's first point about data conversion cost, the TCP/IP
FTP program can transfer files in a standardized network-ASCII or in
a regular binary.  For virtually all systems, the former requires
character-at-a-time scan and convert, whereas the latter involves only
block copies.  It is not unusual for the throughput different to be as
large as a factor of two.
