I had good results by using "renice" to give the uploading ftp process higher priority. Waiting on a busy network link blocks often, and in situations where you've got plenty of bandwidth you actually want ftp to have a lower priority than your interactive traffic. Renice was effective in giving ftp a higher priority.
