YES, and this is worth noting:

IF your two systems are the same hardware, software (even if they're not
you can try this) try setting FTP to 'type binary' (binary transfer.)
Default on 4.2 is 'text', which means things like newlines are getting
translated to CR-LF and back which means character processing which means
slowing you down. 20KB/s is a typical upper limit (well, average upper limit)
for 'text' transfers between two vaxen over an ethernet. You will see
dramatic speed-ups if you try binary. Try it once and verify that what
gets to other side is what you want (if it is any unix-unix it probably
is, but you need to check this.)

Also (I bet you get this answer a lot) rcp should be similar in speed to
ftp binary.
