The FTP protocol is really slow for many small files because of the many roundtrip commands and replies, and the new data connection for each file. The only way you're going to achieve a decent speed is by using multiple connections. (or changing protocol :) - if you don't need to specifically support FTP servers, have a look at rsync - not sure if the protocol is open, but it supports pipelining and zlib compression making it very fast).
