So some questions. Are the ftp sessions from a local LAN, or from
the internet where the far end is broadband, or with the far end
on dial-up?

With telnet always fast and ftp slow on some connections it
sounds like it could be packet sizes on one of the machines are set
too high and thus have to be split. Ftp is going to use large
segments while telnet is going to be using quite small packets.

This is just a thought. You might try dropping your MTU down to
20-30 bytes below 1500 in case some machine isn't correctly
dropping them down. And if any of these are using dialup to access
the net you might check to see if the MTU is about 552.

This may be way off base, but it's worth checking.
