Doug Comer's team was the part of CSNet that did the IP/X.25 driver. As
I recall, yes, it had code that put some effort into minimising
connection opens.
Our telephone-based dial-up email relaying by MMDF also sometimes used a
PSTN/X.29/X.25 path. It did not work to minimize connections, since it
worked at much lower access frequencies. However it /did/ have to pay
attention to the dial-up link protocol's packet size and the x.25 packet
size, to reduce the total x.25 packet count.\
