because sometimes, a user in a place with limited connectivity between providers, and especially international providers, gets a much better connection to the cdn node, and the cdn node gets a much better connection to the origin, than the user would direct. additionally, cdn node-to-origin typically makes much better use of keepalives; ftp(1) called repeatedly can't do a keepalive at all; so there are fewer delays for handshaking (N x small RTT x 500 packages can save a bunch of time compared to N x large RTT x 500). there really is a big difference in some cases. and if you're somewhere that has good net anyway, you probably have a mirror you can use that is faster than the cdn for all cases, not just snaps. -- Please keep replies on the mailing list.
