Are you sure that's it's just not normal network delay you're seeing.

I've never seen ftp claim that a transfer takes 0.2 seconds when it took really thirty. Is it possible that the ftp command didn't get sent, and when it finally did and the response was received it took only 0.2 seconds? >An ftp transfer of a 218K file started off in a massive burst >where it finished the first 20K in about 5 seconds, then stalled and finally >I gave up.

This sounds like a flow control problem, but they generally show up as hung connections, which yours don't. Are your lines on your box and the remote box setup to use HW handshaking, and is PPP on both ends also setup to use HW handshaking?
