In this case, because of the round trip times of the connection setup and teardown, you may get higher performance with more threads and the smaller files. One thread could be transferring a file while another is setting up or tearing down a connection. It all depends on what resources are your limiting factor.

Dan J. Bernstein (http://www.qmail.org) used this concept in building qmail. While not everyone agrees on his implementation of SMTP, the ability of that server to fully utilize the bandwidth of a host for small messages is hard to argue with.

Update: I am not saying that you will get better performance with multiple threads. It depends on a lot of different factors, both local and remote.
