Discussions focus on issues with TCP window sizes, and how packets are
acknowledged.

I can't see why ftp should be radically different from http - except
that it opens TCP connections both ways if I remember correctly.

Worth checking out local ftp performance. I think the TCP changes were
made in a fairly recent versions of Solaris.

I'm reading some stuff at HP and deja as I think Rick Jones (HP network
performance guru and more recently father) made some comments on the
topic.
