In addition to what Sandra said, the ack is generally in a separate
TCP packet from the next response or request.  That means there's
double the number of TCP packets.  Especially over high latency links,
I think this will be a big help.  I've had plenty of experience of
cross-country remote protocol sessions and I like anything that helps.
