as an additional, but not objectively confirmed datapoint, scp and sftp
perform faster for me than ftp between identical machines.

scp/sftp typically compress the data before encrypting it though the
default setting varies by platform/version. Over a slow connection
but using fast machines this can greatly increase transfer rates if
your data is compressible by a large amount.  If the machine is slow
and the network fast, then the overhead of the compression can
actually slow things down.  compression can be enabled/disabled by
command line options.
