Is net.inet.tcp.path_mtu_discovery=1?

No, it was set to 0. is it supposed to be set to 1? If so, should the default be 1? As far as documentation goes Ive read most of modern UNIX systems have it turned on by default.

It might help.

Does anybody object to turning Path MTU Discovery on by default?
It's been more than 15 years since it was introduced and everybody had a chance to learn about it by now. Is there a technical reason (e.g. related to where the Path MTU is stored), for having it off till now?
