You're wrong:

ftp> get Musopen-DVD.zip
local: Musopen-DVD.zip remote: Musopen-DVD.zip
229 Extended Passive mode OK (|||30016|)
150-Accepted data connection
150 2357995.9 kbytes to download
100% |***********************************|  2302 MiB   96.71 MiB/s    00:00 ETA
226-File successfully transferred
226 24.191 seconds (measured here), 95.19 Mbytes per second

This is 1000Base-T, with standard cat 5e cable.  scp isn't much slower.
